=Summary=

Teaser
It is the spring of 2000. Yagami Taichi is on his father's computer, writing an apology email to Takenouchi Sora for an incident that occurred a few days prior, but when Yagami Hikari interrupts him, he accidentally adds a love heart to its end. Hikari tells him that she is about to leave for a birthday party, and he attempts to snatch the present she is bringing. Once he gives up, she reaches around and clicks to send the email, complete with the unwanted love heart, and Taichi panics. As Hikari leaves and their mother, Yagami Yuuko, returns home from grocery shopping, Taichi is notified that the email was rejected and could not be sent.

Meanwhile, Izumi Kōshirō is browsing the internet at home. When he examines the source of a web page, it suddenly turns into rapidly moving gibberish. On closer examination, a webpage opens that reveals a Digitama generating as people around the world look on. The Digitama hatches, and sends Kōshirō an email consisting of only one word:


 * hello!

Act One
As Taichi laments that Hikari is getting cake at the birthday party, Yuuko volunteers to bake him a cake. At that moment, Kōshirō arrives at the Yagami residence, having rushed over to talk to Taichi about the Digitama.

On Kōshirō's laptop, the two examine the hatched Digimon, Kuramon: a species of Digimon that neither have ever seen before, which they nickname "the jellyfish". Kōshirō shares with Taichi the results of a Russian friend's analysis of the the Digitama's data, which indicates that it was formed by the conglomeration of various computer bugs. At that moment, it evolves into Tsumemon and sends them an email (from the email address @@@@@@djm.factorymark.co.jp ):


 * I'M HUNGRY

It begins eating massive amounts of data from the internet, making computers and electronic systems everywhere go haywire. The disruptions that it causes make the television news. Kōshirō surmises that eating data is how it evolves.

Taichi and Kōshirō rush to the study to use Taichi's father's computer again (on the way, Kōshirō accepts a glass of Oolong tea from Yuuko). By the time they arrive, the Digimon has evolved into its Child form, Keramon. Gennai, Agumon and Tentomon contact Taichi and Kōshirō, and the partner Digimon volunteer to enter the internet to track it down and destroy it, to repay the Chosen Children for saving the Digital World.

While Gennai initiates the process of transferring Agumon and Tentomon into the internet, Taichi attempts to contact the other six Chosen Children to recruit them. However, none of them are available:
 * Kido Jo is taking his middle school entrance exam
 * Ishida Yamato and Takaishi Takeru are visiting their grandmother, Kinu, in ; Taichi gets Kinu's number and reaches her, but she hangs up on him by mistake
 * Tachikawa Mimi is not home, and Taichi gets her answering machine
 * Taichi succeeds in reaching Hikari at the birthday party, but she feels obliged to stay at the party
 * Kōshirō reaches Takenouchi Toshiko (Taichi insists that he call instead), but when she tells Sora that "the Yagami residence" is calling, Sora refuses to take the call and tells her mother to say that she is "not home"

Sora checks her emails, expecting an apology from Taichi, but no new emails arrive.

Agumon and Tentomon arrive in the internet and track down Keramon to a site where it is consuming data. It does not notice their entry, so they attack it while it is distracted. Their attacks have no apparent effect. Keramon sends Taichi and Yamato another email:


 * PLAY?

Agumon and Tentomon evolve into their Adult forms, Greymon and Kabuterimon. Just as Greymon hits it with his, Keramon evolves again, into Infermon. Kōshirō initially assumes that it is also Adult level, but Infermon proves to be completely invulnerable to Greymon and Kabuterimon's attacks, and its own technique causes the two significant damage. Kōshirō realizes that he misjudged Infermon's level and that it is actually Perfect, having skipped a level. In response, Taichi and Kōshirō have Greymon and Kabuterimon Super Evolve to catch up, but Infermon attacks them while they are still in the process of evolving, causing them to devolve back into Agumon and Tentomon. Infermon flees the scene.

Act Two
Taichi and Kōshirō begin receiving emails from children around the world who witnessed the fight, as well as a new email from Infermon:

Kōshirō notices Infermon's email address— @@@@@@djm.ntt.co.jp/sys/switchboard —and realizes that it has gotten into 's telephone system. Taichi attempts to get ahold of the others again, but other than Hikari (who still cannot get away from the party), he is unable to reach any of the others because their lines are busy. They soon learn why: Infermon is spamming all of NTT's phone numbers, including Taichi's, with calls from a computerized voice that repeats the word "hello" over and over, in an attempt to bring the system down. Infermon's tactic also disconnects their internet connection and renders it unusable going forward.

Meanwhile, Yamato attempts to call Taichi back, but fails to get through because of Infermon.

Kōshirō runs home for reasons he does not immediately explain. Taichi walks in on Yuuko watching a news bulletin talking about the problems with the phone system, and overhears it talking about the emergency voice mail system. Inspired, he uses it to get messages to the other Chosen Children.

Sora receives Taichi's message and comes to his apartment. However, just as she is about to knock on the door, she decides against it due to her grudge against Taichi, and walks away in a huff.

When Taichi tries sending Mimi a message, his mother overhears and shares with him a postcard from her that just arrived, revealing that she is out of the country for a holiday in Hawaii.

Kōshirō returns to the apartment with a satellite cell phone, which enables direct connections to foreign access points, allowing them to bypass NTT's clogged switchboard for their internet connection, but unable to help with making calls within Japan. At Kōshirō's suggestion, Taichi checks the emergency voicemail, and finds that Yamato has left them a message. Taichi and Kōshirō, and Yamato and Takeru, exchange messages to update the latter two on the situation and ask them to find a PC with an internet connection. Yamato is skeptical of their odds of finding a computer in Shimane, but they head out to try anyway.

When the satellite internet connection is established, Taichi and Kōshirō find that Infermon is gone. Infermon then emails them:


 * NOT HERE NOT HERE BOO

Kōshirō notices the email address: @@@@@@djm.dot.gov.ny.us. The domains are now those of a government email adress from New York in the United States.

Yamato and Takeru visit households and businesses in Shimane, trying to find a computer. The only one that they find, inside an electrical appliance store, is not hooked up to the internet. The shop's deliveryman volunteers to take them on a ride to find a computer with internet.

Meanwhile, Infermon begins causing havoc in the US. Its face appears on screens around the place.

Yamato and Takeru find an internet-enabled computer in a barbershop, and are permitted to use it while the deliveryman has a shave. They contact Taichi and Kōshirō via video chat. Kōshirō asks Taichi if he can have his Oolong tea.

Act Three
Agumon and Tentomon return to the internet to track down Infermon, and are joined by Gabumon and Patamon. Kōshirō guides the four to Infermon's location. They find Infermon standing in the middle of the area, with a large arrow pointing to him and a pop-up that reads:


 * OVER HEEEERE

Yamato realizes that Infermon is toying with them, so he and Taichi have Gabumon and Agumon Warp Evolve into their Ultimate forms, Metal Garurumon and War Greymon. Children all around the world are tuned into their computers, ready to watch the battle.

Patamon attempts to evolve as well, but before he can finish, Infermon evolves into its own Ultimate form, Diablomon, and squashes both Patamon and Tentomon, taking them out of the fight. In retaliation, War Greymon and Metal Greymon press a fierce offensive against Diablomon and are evenly matched. Meanwhile, Kōshirō is left with no choice but to run to the bathroom because of all the Oolong tea that he has drunk.

War Greymon and Metal Garurumon have Diablomon pinned down and are charging their attacks to hit, but something is slowing them down, and their attacks miss Diablomon entirely. In frustration, Taichi shakes his computer's monitor, and the computer crashes entirely, cutting them off from the fight. Unbeknownst to Taichi, War Greymon has stopped moving.

When Kōshirō returns, he is enraged at the sight of the crashed computer, and accuses Taichi of having caused it. The two bicker about it, and Kōshirō accuses Taichi's attitude of being the reason that he and Sora are bickering. This stops Taichi in his tracks, and he admits the reason that he and Sora are not getting along is that he had gotten her a hairclip as a birthday present, and she had interpreted it as meaning that he does not like her hat.

Once the computer is rebooted and Kōshirō re-establishes the connection, they log back in and find that in their absence, Diablomon has overwhelmed and caused major damage to both War Greymon and Metal Garurumon. Taichi laments that he had not been there to help. Meanwhile, Kōshirō reads through the emails that they are receiving from the children watching the fight, most of which are disparaging the two for having failed when they had the advantage over Diablomon. Taichi snaps at Kōshirō for reading them out loud at such an inappropriate moment, and Yamato breaks up the fight.

Meanwhile, somewhere else, Diablomon is holding a clock.

Taichi, Kōshirō, Yamato and Takeru receive an email from Diablomon:


 * WHOOO'S GOT THE CLOCK?

A ten-minute countdown appears on their screens, and behind it, an image of Diablomon begins multiplying. Kōshirō receives an email from a middle-schooler in Taiwan, who has found through hacking into 's computers that thirty minutes prior, a bug in their system—which Kōshirō realizes is Diablomon itself—triggered the launch of a nuclear missile from a US military base. They have no information on its present location or target, and conclude that with its specifications, it could strike anywhere on the planet.

Emails continue to roll in, taking on a more supportive tone, cheering them on to finish the fight.

Kōshirō concludes that as long as the fuse does not activate, the missile will not detonate, and that Diablomon is challenging them to a game to find the one Diablomon who is holding the clock that governs the detonation countdown. If they can kill that Diablomon, they can stop the countdown and prevent the missile from detonating.

Despite their injuries, War Greymon and Metal Garurumon get to their feet and volunteer to stop Diablomon. Kōshirō sends them the address.

7:00 to go on the missile countdown. The timer, coincidentally, lines up with both the remaining cook time on Yuuko's cake and the time left in Jo's exam. War Greymon and Metal Garurumon travel through the internet in pursuit of Diablomon, while massive numbers of emails from children around the world—including Inoue Miyako and Akiyama Ryo—pour into Kōshirō's inbox.

6:30 to go on the missile countdown. War Greymon and Metal Garurumon arrive in an environment whose walls are swarming with countless Diablomons. Kōshirō estimates that they number in the 16,000s. All of the Diablomons begin bombarding War Greymon and Metal Garurumon with their attacks, easily overwhelming them. Takeru notices that something is not right with War Greymon and Metal Garurumon's movement, and Kōshirō realizes that all of the incoming emails are slowing down their processing speed. Kōshirō attempts to communicate to all of their viewers that they must stop sending emails.

The Diablomons stop firing, and the dust clears. War Greymon and Metal Garurumon have stopped moving and are critically wounded.

5:00 to go on the missile countdown. Distraught, Taichi, breathing heavily, silently reaches out to his computer screen, as if to reach War Greymon.

Yuuko enters the computer room and finds that Kōshirō is muttering to himself about the emails, and Taichi is gone.

Through their computer screens, Taichi and Yamato enter the internet and try to rouse War Greymon and Metal Garurumon, promising that they will be there to fight with them. All of the supportive emails manifest around them, forming an egg-like cocoon, and War Greymon and Metal Garurumon are empowered by Taichi, Yamato and the emails to fuse together into a new Digimon: Omegamon.

1:50 to go on the missile countdown. The Diablomons resume firing on Omegamon, but Omegamon deploys its and swings it to deflect their blasts back at them, wiping out a significant number of them. Omegamon finishes off the rest of the Diablomon copies with several blasts.

1:00 to go on the missile countdown. When the dust clears, only one Diablomon is left: the one with the clock. Omegamon attempts to aim at it, but it is moving too fast for Omegamon's response time to track. Meanwhile, the missile begins its descent.

0:30 to go on the missile countdown. Kōshirō realizes that they can turn the same processing speed weakness that War Greymon and Metal Garurumon had against Diablomon. He redirects all of the children's emails to Diablomon's email address, which immediately slows it to a crawl.

0:10 to go on the missile countdown. Omegamon finds Diablomon and pounces upon it.

0:02 to go on the missile countdown. Diablomon attempts to retaliate with, but it is too slow. Omegamon plunges the into its head, shattering the clock and stopping the countdown. Diablomon's lifeless body splits in half and sloughs off the clock.

The missile lands in. At first, Kōshirō thinks that they did not make it in time, but the missile does not detonate. Taichi returns to the apartment, and the two collapse over their balcony as they watch the missile sink into the bay.

Yuuko's cake is ruined, and she is confused as to how, since her microwave has computer control. Meanwhile, Sora finally receives Taichi's apology email. She sees the love heart that he left in, and is amused. She replies to the email, apologizing and thanking him for the gift, and encloses a photograph of herself wearing the hairpin.

Soundtrack

 * Main article: Digimon Adventure: Our War Game! - Original Soundtrack

=Reception= Volcano Ota has described Our War Game! as being known to Digimon fans as the "monumental work" of the Digimon films.

Our War Game! and the preceding short film have been credited with bringing director Hosoda Mamoru to the attention of head producer, who is said to have identified him as a potential successor to  on the basis of his work on the two short films. This led to a brief tenure at Studio Ghibli in which Hosoda was, for a time, attached as the director of , although he departed both the project and the studio over creative differences before its completion.

In Other Media
The events of Our War Game are discussed on several occasions in Digimon Adventure 02.
 * In, when the Chosen Children are trading stories about encounters that they had with Digimon prior to becoming Chosen Children, Inoue Miyako mentions that she witnessed the fight with Diablomon and sent emails of support to the Chosen Children, as she was depicted doing in Our War Game! The group theorizes that these events, including Miyako's experience with Diablomon, are the reasons that they become Chosen Children. Miyako's comments also date the events of Our War Game! to the spring of 2000. A flashback is shown which recreates Miyako's Our War Game! cameo, complete with Inoue Momoe at her side.
 * In, Izumi Kōshirō tells Motomiya Daisuke's group of Chosen Children that Paildramon is not the first time that two Digimon have fused together to evolve, and that there is precedent in Omegamon (this is also the first time that Omegamon's name is spoken on-screen).
 * In, Kōshirō shares the aforementioned theory about the cause of becoming Chosen Children with Ichijouji Ken, and mentions Miyako's experience with the Diablomon battle. Ken mentions that he also had an experience around that time, in August 2000, but can no longer recall it.

Digimon Adventure 02: Tag Tamers opens with Ken and Akiyama Ryo watching the Diablomon battle, indicating that like Miyako, the events of Our War Game! are the mentioned experience that he could no longer recall from "Today Miyako is in Kyoto". While Ryo does indeed make a cameo watching the battle in Our War Game!, the location is radically different: Tag Tamers depicts him and Ken watching on a PC in Ken's bedroom, but Our War Game! depicts Ryo on a laptop in the mountains, with another child who is not Ken.

Digimon Adventure 02: Diablomon Strikes Back is a direct sequel to Our War Game! It also features a battle between Omegamon and Diablomon in the internet which plays out similarly to the Our War Game! battle and replicates its art style.

The PlayStation Portable game adaptation of Digimon Adventure includes a chapter that adapts Our War Game!

In Digimon Adventure: Last Evolution Kizuna, the first encounter with Eosmon is an homage to Our War Game! The battle also occurs in a non-Digital World cyberspace, the same four Chosen Child/partner Digimon pairs as in Our War Game! (Yagami Taichi and Agumon, Ishida Yamato and Gabumon, Kōshirō and Tentomon, and Takaishi Takeru and Patamon) participate in the fight, they travel to the site of the battle through virtual tunnels of the same style as those in Our War Game!, and the fight culminates in the formation of Omegamon.

The second and third episodes of the reboot Digimon Adventure: are based on Our War Game!, differing in that the Algomons replace Diablomon, and that this version of events is Taichi, Yamato and Koshiro's first experience with Digimon. The second episode is also titled "War Game".

Taichi and Yamato's Omegamon is a playable character in Digimon Tamers: Battle Spirit and Digimon Tamers: Battle Spirit Ver. 1.5 (as the temporary evolution of Yamato's Gabumon and a special version of Agumon) and Digimon Tamers: Battle Evolution (as a separate unlockable playable character in its own right). In Battle Evolution, when Omegamon is selected, Taichi and Yamato are depicted in their Our War Game! attire on the pre-battle screen by default (if the L1 Button is held when selecting Omegamon, they are instead depicted in their Digimon Adventure 02 school uniforms).

Outside the Digimon franchise, later in his career, director Hosoda Mamoru revisited the basic plot and premise of Our War Game! in another, non-Digimon film: . In an interview, Hosoda described Summer Wars as "the feature-length version" of the idea that he had for Our War Game!, free of the constraints of the 40-minute runtime that Toei Animation imposed on him for Our War Game!

=Edits=

English
Our War Game! was used as the second part of the English dub production Digimon: The Movie.

The extent of the edits and rewrites to the three films that comprised The Movie, including Our War Game!, was such that in 2000, the resulting dissimilarity to the original films was used by the as grounds for a legal action against, the studio which at the time held the US rights to the Digimon anime and which produced The Movie. SAG argued that The Movie no longer constituted a "dub" under the terms of their dubbing agreement with Saban due to the "significant" extent of its "revisions, reformatting, additions, deletions and modifications", and therefore they sought for the English voice cast to be paid residuals for subsequent television broadcasts and home media releases, which they would not have been owed under the terms of the agreement had The Movie met its definition of a dub.


 * As usual for English dubbed Digimon productions, the score is totally replaced and nothing remains of the Japanese soundtrack in The Movie. Unlike other dubbed productions, The Movie uses licensed pop songs from the US in addition to the usual score from their dubs of the Digimon Adventure and Digimon Adventure 02 television series.
 * In Our War Game!, insert songs for evolution scenes are used only once, when Agumon and Gabumon Warp Evolve for the final fight with Infermon/Diablomon ("Brave heart" is played); otherwise, the currently-playing instrumental score is not interrupted at any time that anyone evolves. In The Movie, all instances of allied Digimon digivolving (evolving) interrupt the score with the English dub "Digimon Theme" to accompany their evolutions. These reflect common practices of each version of the rest of the anime: the Japanese version does not exclusively use its evolution insert songs every time that evolutions occur, and only chooses to do so when it fits the tone, context and plot beats of a given scene; while English dubbed versions almost exclusively use their designated theme songs or leitmotifs for evolution scenes, regardless of tone.
 * As usual for the English dubs of Adventure and Adventure 02, dialogue is generally significantly longer-winded, previously nonexistent jokes (sometimes of a scatological nature) are often added, and previously nonexistent dialog is often added over what were originally moments of silence.
 * In Our War Game!, there is no narration. In The Movie, consistent with the other parts of it, Kari Kamiya (Yagami Hikari)—specifically, her eleven-year-old self from Adventure 02—provides narration throughout the film, often irreverent in tone.
 * When she introduces this part of The Movie, a title card declaring "Four Years Later" is superimposed on top of its first shot.
 * The first scene of Our War Game! is a throwback to the first Digimon Adventure film. Leading in from the production logos while Boléro plays, the giant Digitama from the first film is shown descending from the sky while the lights in the Odaiba apartment complex go haywire, then when it opens, the film cuts to the same scene, but in daytime in the present day. This is cut entirely from The Movie.
 * In Our War Game!, when Yagami Taichi is writing his email to Takenouchi Sora, he is finished with it just before Hikari enters the room, but when Hikari enters, he accidentally hits his keyboard in such a way that a love heart is added to his signoff. In The Movie, Tai (Taichi) struggles with some sort of auto-replace feature in the email client impacting his intention to sign off saying "From", instead of "Love", all before Kari enters the room. The Movie 's version of the email that he writes is significantly longer and, unlike Our War Game!, includes an anecdote about him once vomiting in her hat.
 * In addition to editing the footage to replace the Japanese email with English text, The Movie also cuts a few seconds of footage in which Taichi notices that when he typed his given name in (in kana), his computer's IME selected the wrong kanji, and he cycles through different kanji renderings of "Taichi" until he finds the right one. Since The Movie edited the email to be written in English, this would have had no place.
 * Shortly after Hikari sends the email and leaves the room, Our War Game! has a brief scene in which the computer reports that the email could not be delivered, which becomes a recurring plot point on Sora's end in the rest of the film. The Movie cuts this scene, making it seem as if the email was successfully sent, but does not alter any subsequent scenes with Sora to reflect this cut.
 * In Our War Game!, Hikari makes no mention of what is in the birthday gift she has gotten for her friend. In The Movie, Kari says that it is "a pink Power Ranger", right as Tai begins reaching out to snatch it from her. This is added product placement: at the time of The Movie 's production, Saban Entertainment also held the rights to the ' franchise, which they retooled into '.
 * In Our War Game!, Kuramon only vocalizes one line of dialog in its Diablomon form, and otherwise, the only vocalization that it makes in any form is faint giggling. In The Movie, it has significantly more spoken dialog.
 * A consequence of this is that, in Our War Game!, the Chosen Children never have any way to learn or know the names of any of Diablomon's forms, and only ever refer to it as "the jellyfish", a "Digimon", or simply "it" . In The Movie, since it verbally introduces itself to them as Keramon upon attaining that form, and says its names when it announces its subsequent evolutions, the DigiDestined call it by its current form's name from Keramon onward, although they still use the "jellyfish" nickname for its Kuramon form on two occasions.
 * Our War Game! 's opening credits are removed, as The Movie had its own opening credits with its own made-up footage prior to its first segment. The footage played between the credit slides in Our War Game! is repurposed as a montage over which a licensed pop song, ' "", plays.
 * During the opening credits of Our War Game!, there is a scene of the front door of Tachikawa Mimi's apartment. Next to the door is a heart-shaped plaque identifying the inhabitants (Mimi and her parents), which falls off the wall while they are on holiday. In The Movie, the writing on the plaque is edited to turn it into a Valentine from Joe Kido (Kido Jo).
 * In Our War Game!, Izumi Kōshirō's contact who gave him insight into what Kuramon is is Russian, but they are unnamed and nothing is made of their identity. In The Movie, the character is instead identified as Willis (Wallace) from Digimon Hurricane Landing!!/Transcendent Evolution!! The Golden Digimentals, which comprises the third part of The Movie. The Movie version of Our War Game! greatly expands the role of this contact under the Willis identity in the rest of the film:
 * Some emails that Izzy (Kōshirō) receives are edited to make Willis their sender, and the footage is edited to replace the avatar on the relevant emails with his face.
 * In both versions, the contact is described as a prodigy who is taking university/college classes despite being in elementary school. In the case of The Movie, while the line itself is otherwise accurate to the Japanese version, its retention in a context where Willis is the character it is describing attributes a previously non-existent detail to his profile, as in Hurricane Touchdown!!/Transcendent Evolution!!, Wallace is not indicated to be anything academically special or to have any particular affinity for computers.
 * In Our War Game!, Taichi responds to Kōshirō's discussion of the Russian friend's academic background by lamenting that he only gets to take elementary school classes despite their similarity in age. The Movie changes this into Tai attempting to brag, "So what? I'm in junior high school, and I take classes in junior high school!" (At this point in the Digimon Adventure timeline, Taichi is not in junior high school.)
 * For the rest of the runtime of The Movie 's version, Izzy's dialog is periodically changed to add further references to Willis's significance in events:
 * In Our War Game!, after the first fight with Infermon, Kōshirō remarks on Infermon's childish nature and on how, even if others recognize the nature of the havoc being played with electronic systems, nobody else is likely to know that a Digimon is responsible. In The Movie, these points are replaced entirely with Izzy tracking Infermon's movements to the United States, and him deciding to warn Willis that Infermon is headed toward him.
 * In The Movie, Izzy credits Willis with giving him the idea to find a way to slow Diaboromon (Diablomon) down.
 * Although the Our War Game! part of The Movie does not explain why he is involved, the Transcendent Evolution!! part was rewritten to reveal that in The Movie 's version of events, Willis was inadvertently responsible for the creation of Diaboromon in the first place.
 * In The Movie, the content of email that they receive from Infermon once the satellite internet connection is established is completely changed, replacing what was originally Infermon taunting them ("NOT HERE NOT HERE BOO" ) with a threat that Infermon is actively seeking out Willis: "I'm close to him."
 * During the first montage of Tsumemon's impact on electronic systems, in Our War Game!, there is a brief scene where a woman in a grocery store finds packets of tuna belly and chub mackerel that are drastically overpriced at ¥1,000,000 each. This is cut entirely from The Movie.
 * A sequence where several civilians are trapped on the malfunctioning Ferris wheel, demonstrating the havoc on digital systems that Kuramon is causing, is cut entirely from The Movie.
 * In Our War Game!, the food and drink that Yagami Yuuko prepares or offers to prepare is entirely normal, and Kōshirō spends the movie drinking Oolong tea that she serves. In The Movie, this is all replaced with jokes about her making strange and disgusting culinary creations, including "spinach cookies", "beef jerky shakes" and "potato juice", and an unspecified unpleasant drink replaces the Oolong tea from Our War Game! as the drink that Izzy consumes throughout the The Movie version, with multiple instances of dialog changed to add Tai calling attention to how disgusting it is.
 * In Our War Game!, during Gennai's conversation with Taichi and Kōshirō, when the other partner Digimon come through a door to join the call, Taichi acknowledges their arrival. In The Movie, this is replaced with each of them saying their own name.
 * A side effect of this is that Gomamon, Palmon, Biyomon (Piyomon) and Gatomon (Tailmon) only have dialog in The Movie version of Our War Game!, even if it consists only of their own name (however, their Japanese voice actors are credited for the roles in Our War Game!). This is also the only dialogue that Gomamon, Palmon and Biyomon have in any part of The Movie.
 * In The Movie, during Gennai's conversation with Taichi and Kōshirō, there is an added reference to the Dark Masters, in which Agumon says that they were "cupcakes compared to (Keramon)".
 * In Our War Game!, when Taichi calls Jo's family, he is told that Jo is away taking his middle school entrance exam. In The Movie, this is changed to Tai just being told that Joe is taking a "test", to which he laments that Joe is "the only kid I know who volunteers for summer school!"
 * The Movie also cuts a few seconds of footage from this scene which depict Jo outside the exam building, rushing to get to the exam in time. Instead, it starts its view of Joe's whereabouts inside the exam room.
 * In Our War Game!, unlike the televised Digimon Adventure anime, none of the Digimon ever announce the names of their attack techniques. The Movie adds technique announcements.
 * In both versions of the film, Keramon sends Taichi and Kōshirō an email with technically similar content relating to "playing", but with divergent tones. In Our War Game!, the email simply reads "PLAY?", indicating a simplistic, childlike tone. In The Movie, the sentiment is altered to make its message more defiant and less immature: "So you like to play games, huh?"
 * In Our War Game!, Greymon and Kabuterimon do not speak while evolving into their Perfect forms, Metal Greymon and Atlur Kabuterimon. In The Movie, Greymon announces his evolution in the usual style.
 * One of the emails that Kōshirō receives after Infermon defeats Metal Greymon and Atlur Kabuterimon—a Singaporean girl berating them for losing even though the fight was two against one—is cut from The Movie.
 * In Our War Game!, after the first fight with Infermon, Taichi makes a second call to Hikari at the birthday party which interrupts a game of cards that she is winning. This scene is cut entirely from The Movie.
 * A B-roll shot of a crosswalk in Odaiba, originally shown while Taichi leaves a voicemail for Jo, is cut from The Movie.
 * In Our War Game!, the contents of Mimi's postcard are shown on-screen and Taichi continues to talk while examining the card; the scene then cuts to Mimi in Hawaii, where she remarks on how nice it is. In The Movie, the footage is the same, but Mimi's dialog is changed to be her narrating the contents of the postcard over both the footage of the card and the footage of her in Hawaii.
 * The scene where Taichi, Kōshirō, Yamato and Takeru have their voicemail conversation is shortened in The Movie, removing 21 seconds of their conversation and, along with it, footage of Taichi and Kōshirō in the computer room.
 * In Our War Game!, there is an extended sequence of Yamato and Takeru going around, trying to find a computer with internet access. This is cut entirely from The Movie.
 * In Our War Game!, when Kōshirō is using a satellite cell phone to re-establish an internet connection, he says that it enables them to directly connect to a foreign access point instead of going through a network switch. In The Movie, Izzy calls it a "satellite uplink" and claims that it will get them back online by "tapping into the military's satellite systems".
 * In Our War Game!, when Agumon, Gabumon, Patamon and Tentomon arrive to confront Infermon, it is silently standing next to a sign that reads "OVER HEEEERE" . In The Movie, the sign is unedited and left in Japanese, but Infermon's intended messaging is changed because it has an added spoken line of dialog: "I'm looking for the programmer—don't interfere!" This further alludes to the Willis plot, as the line "Don't interfere!" later recurs in The Movie 's version of Digimon Hurricane Landing!!/Transcendent Evolution!! in relation to Kokomon, its rewritten and recharacterized version of Wallace's partner Chocomon.
 * In Our War Game!, in the first stage of the Diablomon fight building up to the computer crash, the film toys with its use of "Brave heart". It plays normally over the evolution sequence, cuts out when Patamon is injured, comes back in to its second verse when War Greymon and Metal Garurumon begin to overwhelm Diablomon in retaliation, begins stuttering and skipping repeatedly at the "Show me your brave heart" line when Kōshirō leaves for the bathroom and the computer is about to crash, then cuts out entirely once the computer crashes. The Movie makes no attempt to replicate this with its own score.
 * In Our War Game!, the reason that Kōshirō needs to leave for the bathroom is simply to relieve himself due to all of the Oolong tea he has drunk. In The Movie, it is because he needs to vomit after consuming Yuuko's comically grotesque drinks.
 * In Our War Game!, when Diablomon begins multiplying, its email to Taichi and Kōshirō reads "WHOOO'S GOT THE CLOCK?" . In The Movie, it reads "Who can count backwards from ten?"
 * In Our War Game!, the film is silent when the email is displaying, except for a beeping noise as each kana appears. In The Movie, Tai reads the email out as it appears, and then adds a snide comment, "Is he giving us a math test?"
 * In Our War Game!, after the missile countdown begins, there is a brief incidental scene in the Shimane barbershop where clouds begin to gather and Yasuko, an elderly woman in the barbershop, asks Yamato and Takeru to give their grandmother a bag from her. This is cut from The Movie.
 * The estimated count of Diablomon copies is greatly inflated in The Movie. In Our War Game!, the highest estimate that Kōshirō ever gives is 16,000. In The Movie, Izzy estimates that at its peak, there are "over a million".
 * In Our War Game!, Kōshirō surmises that the detonation of the missile is linked to a counting-down clock that is in the possession of one of the Diablomon copies, and that finding that Diablomon is their goal. In The Movie, Izzy instead talks about destroying the original Diaboromon to make all of the others disappear, and the clock and its significance to the missile are not mentioned at all, even though all footage involving the clock itself is still present and unedited.
 * The Movie rewrites dialogue to establish that Diaboromon has launched two missiles, one of which is explicitly stated to be aimed directly at Tai and Izzy in Odaiba. In Our War Game!, there is only the one Peacekeeper missile, and while it does eventually land in Odaiba (but does not detonate), its target is a mystery to Taichi and Kōshirō beyond knowing that it has the range to strike anywhere in the world. The Movie also omits Kōshirō's discussion about the missile's specifications, including the "Peacekeeper" name.
 * In Our War Game!, when War Greymon and Metal Garurumon arrive for the final confrontation against the Diablomon copies, they all repeat the line "Over here" in a high, cartoony, barely audible voice. In The Movie, the Diaboromon copies are instead all saying "Go back to the beginning" in its usual dubbed voice, which is deep and gruff. As with the "Don't interfere" line, this serves to further the connection between The Movie 's versions of Diaboromon and Kokomon.
 * In Our War Game!, the Chosen Children do not realize that the emails are impairing War Greymon and Metal Garurumon's processing speed until the last fight with the Diablomon copies, when Takeru points out that something is wrong. In The Movie, Izzy has this realization earlier, in the scene where WarGreymon and MetalGarurumon are preparing to pursue Diaboromon, replacing Kōshirō's Our War Game! dialog about how he is sending the two Digimon Diablomon's current address. His dialog for the realization in the last Diaboromon fight is not substantially changed from Our War Game! despite this alteration, so in The Movie, he effectively comes to this conclusion twice.
 * In Our War Game!, the scene where Taichi reaches out to War Greymon in the computer and begins to enter the internet is silent, except for Taichi's breathing. The Movie adds dialog from Tai over this scene.
 * In Our War Game!, Taichi and Yamato's Omegamon does not speak or make any vocalizations at all, as is customary; as such, its name is never spoken or revealed in the film. In The Movie, Omnimon (Omegamon) speaks, voiced by both WarGreymon and MetalGarurumon's voice actors, Lex Lang and Kirk Thornton, speaking the same lines simultaneously.
 * At the one minute mark on the missile countdown, Our War Game! has no dialog over the footage of the missile beginning its descent. The Movie adds radio chatter from an anonymous military squad leader, a character who does not exist in Our War Game!, who reports that he had attempted and failed to destroy the missile and prevent it from impacting.
 * In The Movie, some footage from the final scene when the countdown is stopped is cut and rearranged. In Our War Game!, the missile's landing is shown first; followed by Sora receiving Taichi's apology email; followed by Kōshirō running out to the balcony to witness the landing of the missile, thinking that they did not make the deadline; before the film cuts back to the internet, where Diablomon's body falls apart to reveal that Omegamon's sword has pierced the clock, followed by a cut back to a close-up of Taichi's email. In The Movie, the shot of Diablomon's body falling apart is played first, followed by the missile landing, followed by the scenes with Sora put together; the shot of Kōshirō running out to the balcony is cut entirely, although the second shot of him on the balcony still plays as normal afterward.
 * In Our War Game!, as in most of the rest of the movie, Diablomon is entirely silent when it is killed. In The Movie, Diaboromon has two lines when it is killed: when Omnimon stabs it, it says "Connection... terminated...", and when its corpse sloughs off the clock, it says its last word, "Willis...", continuing The Movie 's pattern of trying to retrofit Wallace into its origin story.
 * Our War Game! 's closing credits are cut entirely, in favor of the combined closing credits of The Movie which run after the Transcendent Evolution!! part. The footage that plays in the background of the original credits is not repurposed anywhere (The Movie 's credits are played over a black background), so as a side effect of this, the payoff of Our War Game's Taichi/Sora subplot—Sora's email reply—is entirely absent from The Movie.
