History CanonWelding / VideoGames

* In 2011, Creator/BandaiNamcoEntertainment merged parts of the previously unrelated (despite numerous [[ShoutOut Shout-Outs]]) ''VideoGame/{{Galaxian}}''[=/=]''VideoGame/{{Galaga}}'' series, ''VideoGame/AceCombat'' series, ''VideoGame/RidgeRacer'' series, and some other games [[note]][[https://ugsf-series.com/en/ including]] ''VideoGame/{{Bosconian}}'', ''VideoGame/DigDug'', ''VideoGame/{{Baraduke}}'', ''VideoGame/MrDriller'', ''VideoGame/{{Starblade}}'', and ''VideoGame/MizuiroBlood''[[/note]] into an overarching ''[[http://acecombat.wikia.com/wiki/United_Galaxy_Space_Force_(series) United Galaxy Space Force (UGSF)]]'' series. ''VideoGame/AceCombat3Electrosphere'' [[Timeline/UGSFSeries serves as its starting point]].

* Again, par for the course regarding ''VideoGame/SuperRobotWars'', due to their MassivelyMultiplayerCrossover nature, but the specific example goes to ''VideoGame/SuperRobotWarsOriginalGeneration'', having the unenviable task of integrating the countless OriginalGeneration stories from previous ''Super Robot Wars'' installments into a cohesive UltimateUniverse, often filling in the blanks left by licensed characters with its OriginalGeneration. For example, the "[[AMechByAnyOtherName Choukijin]]" from the ''VideoGame/SuperRobotWarsAlpha'' saga were originally connected to the ''Anime/MazingerZ'' mythos; in ''Original Generation'', they were created to combat the [[EldritchAbomination Einsts]] from ''VideoGame/SuperRobotWarsCompact2''. A later ''Original Generation'' installment, including at least [[VideoGame/SuperRobotWarsZ one licensed saga]], places more emphasis on space-time dimensional elements, a handy way of working in anything that can't be shoehorned in thoroughly into main {{Continuity}}, but also working around obstacles that might violate pre-established canon. From there, the ''VideoGame/EndlessFrontier'' games tie into ''VideoGame/NamcoXCapcom'' and the ''VideoGame/{{Xenosaga}}'' series, all of whom preceed ''VideoGame/ProjectXZone''; {{Sequel}}s the ''Second Original Generation'' and ''The Moon Dwellers'' even made preceding {{Crossover}}s (''[[VideoGame/AnotherCenturysEpisode Another Century's Episode R]]'' and ''Project X Zone'', respectively) explicitly canon.

** To a lesser degree, ''VideoGame/FarCry'' has a small nod to Abstergo Industries and the Pieces of Eden from the ''Assassin's Creed'' series which indicates that it might also be in the same continuity.

** To a lesser degree, ''VideoGame/Far Cry'' has a small nod to Abstergo Industries and the Pieces of Eden from the ''Assassin's Creed'' series which indicates that it might also be in the same continuity.

* Creator/{{Ubisoft}}'s ''Franchise/AssassinsCreed'' and ''VideoGame/WatchDogs'' take place in the same universe. This was first shown in ''VideoGame/AssassinsCreedIVBlackFlag'' having an in-game email from Blume, a security firm from ''Watch_Dogs'', proposing Abstergo Industries make use of their ctOS system. Furthermore, the COO of Abstergo Entertainment from the same game is said to gone missing suddenly after a business meeting in Chicago, the setting of the first ''Watch_Dogs''. In that game it turns out the Assassins hired Aiden Pierce to take care of the COO for them. While some players of both games originally assumed these to be nothing more than easter eggs, ''VideoGame/AssassinsCreedOrigins'' makes the connection of their universes 100% certain by confirming that yes the mission where Aiden kills the COO of Abstergo Entertainment is part of the official ''Assassin's Creed'' canon.

* ''VideoGame/BlasterMasterZero'' seems to be a straightforward ContiuityReboot of the first game, and while that's still true for the most part (Jason, Fred, and Eve all have different backstories than whatever was previously established), it's also canonically a StealthSequel to ''Metafight'', the original Japanese version of the game ([[spoiler:the heroes from that game created Sophia III and Eve]]).

* ''VideoGame/BlasterMasterZero'' at a first glance seems like a straightforward ContinuityReboot of the first game, plus some elements from other entries in the series. While that is still true (with Jason, Fred, and Eve being different characters), it's also a reboot of the ''original'' Japanese version of Blaster Master, ''Metafight'', which was previously all but forgotten since then.

* ''VideoGame/BetrayalAtKrondor'' and ''[[Literature/TheRiftwarCycle Riftwar]]'', mentioned under Cross-Media.

* Discussed in ''VideoGame/ProjectXZone'' where (on top of canonizing about a dozen other crossover games; see the Cross-Media section above) the characters from the many different universes have some fun trying to link them together. For instance, the characters of ''VideoGame/GodsEaterBurst'' find it plausible that their world would continue on a downward spiral, necessitating the construction of [[VideoGame/ResonanceOfFate Basel]] in their far future. However, it's also acknowledged that certain universes are mutually exclusive with each other (''VideoGame/SakuraWars'' is technologically and geopolitically incompatible with modern Earth) or completely isolated (''VideoGame/TalesOfVesperia'' is shown to be in its own disconnected bubble), so nothing is set in stone.

** ''VideoGame/StreetFighterAlpha'' effectively combined the ''Street Fighter'' and ''VideoGame/FinalFight'' franchises into [[SharedUniverse one shared continuity]] by featuring Guy and Sodom from the first ''VideoGame/FinalFight'' as playable characters, followed by Rolento in ''Alpha 2'' and Cody in ''Alpha 3''. ''Final Fight'' was originally intended to be a {{sequel}} to the [[VideoGame/StreetFighterI first]] ''Street Fighter'', and, most importantly, the two franchises had been already officially part of the same continuity since the console version of ''VideoGame/StreetFighterII'' first came out (proof of this was in the [[AllThereInTheManual instruction booklet]]). By extension, this also puts ''Street Fighter'' in the same universe as ''VideoGame/SaturdayNightSlamMasters'', since both that series and ''Final Fight'' feature the character of Mike Haggar. This is confirmed in ''VideoGame/StreetFighterIII'', where Hugo's ending has him about to enter into a tag-team match against two ''Slam Masters'' characters, who will vary depending on who his partner is (for instance, if Elena is chosen, she and Hugo will face off against Haggar and Black Widow). [[AllThereInTheManual Ancillary material]] released for ''VideoGame/StreetFighterV'' also mentions that Rainbow Mika's coach, Yoko, was forced to retire from wrestling after Black Widow injured her during a match. ''VideoGame/RivalSchools'' has featured Sakura Kasugano as a participant (and establishes her as [[ChildhoodFriends good friends]] with Hinata Wakaba and Natsu Ayuhara; [[https://www.creativeuncut.com/gallery-10/rs-illust-sakura_hinata_natsu.html there's even art of all three hanging out together]]), and Tiffany Lords and Hinata have made cameos in ''V'', with Akira Kazama later joining the playable roster as DLC. And if that wasn't enough, ''VideoGame/CaptainCommando'' exists TwentyMinutesIntoTheFuture of this SharedUniverse, as one of the playable characters, Sho ([[DubNameChange Ginzu]]), is the successor of the Bushinryu ninjutsu utilized by Guy, a connection that is reiterated when they team up in ''VideoGame/NamcoXCapcom''. The very first level happens to be a future (but still crime-ridden) Metro City, and players can find a bust of Haggar that awards 5000 points at certain points throughout the game.

* Having released the humorous ship adventure ''Eye of the Kraken'' and the classical noir ''Carte Blanche: A Fistful of Teeth'', the video game company ''Absurdus'' made a sudden decision to declare the two games a part of the trilogy, and announce the third part ''The Eight Tentacles of the Apocalypse'', in which the Turkish diplomat Abdullah from the first game and the noir detective Edgar Delacroix from the second one join forces to stop the awakening of the Kraken. {{Lampshaded}} [[http://www.absurdus.net/8tentaks/ by the developers themselves]]: "You didn't know these games were part of a trilogy? Neither did we, but it is now an undisputable fact".

** Other SNK titles, from ''VideoGame/SamuraiShodown'' to ''VideoGame/TheLastBlade'' to ''[[VideoGame/FuunSeries Savage Reign/Kizuna Encounter]]'', have been alluded to in varying extents throughout ''KOF''[='s=] run. The latter, in particular, is also part of the ''Fatal Fury/Art of Fighting'' timeline in its original form, as is ''Buriki One''. Both series have had two GuestFighter entrants each in ''XI''.

* In ''VideoGame/BravelySecond'', players can obtain a high-level staff known as [[UsefulNotes/MiyamotoMusashi Musashi's Oar]] from a blue treasure chest in the Witherwoods. The weapon in and of itself alludes to the oar Musashi famously used in his duel against [[UsefulNotes/SasakiKojiro Kojiro Sasaki]], with its description noting Musashi to hail from the island nation of [[{{Wutai}} Wa]] (which vanished centuries before the time of ''VideoGame/BravelyDefault''). The last sentence of the account states "No record remains of his death, but it is said that he was summoned to be a hero for another world." This is a reference to one of Creator/SquareEnix's lesser-known titles from their Squaresoft days, ''VideoGame/BraveFencerMusashi''--specifically the Hero Summon ritual (or "[[GratuitousLatin Vocatus Heroa]]" as it's referred to as in ''[[VideoGame/MusashiSamuraiLegend Samurai Legend]]''). The implication is that the ''Musashiden'' games, or at least their version of Musashi, are therefore canon to the setting of the ''Bravely'' series--an interesting thought given that [[spoiler:the BigBad of ''Samurai Legend'' is actually the real-life Kojiro Sasaki, never mind a presumably different Kojiro from Musashi's home world serving as his rival throughout ''BFM'']].

** ''VideoGame/StreetFighterAlpha'' effectively combined the ''Street Fighter'' and ''VideoGame/FinalFight'' franchises into [[SharedUniverse one shared continuity]] by featuring Guy and Sodom from the first ''VideoGame/FinalFight'' as playable characters, followed by Rolento in ''Alpha 2'' and Cody in ''Alpha 3''. ''Final Fight'' was originally intended to be a {{sequel}} to the [[VideoGame/StreetFighterI first]] ''Street Fighter'', and, most importantly, the two franchises had been already officially part of the same continuity since the console version of ''VideoGame/StreetFighterII'' first came out (proof of this was in the [[AllThereInTheManual instruction booklet]]). By extension, this also puts ''Street Fighter'' in the same universe as ''VideoGame/SaturdayNightSlamMasters'', since both that series and ''Final Fight'' feature the character of Mike Haggar.

[[AllThereInTheManual Ancillary material]] released for ''VideoGame/StreetFighterV'' also mentions that Rainbow Mika's coach, Yoko, was forced to retire from wrestling after Black Widow injured her during a match. ''VideoGame/RivalSchools'' has featured Sakura Kasugano as a participant (and establishes her as [[ChildhoodFriends good friends]] with Hinata Wakaba and Natsu Ayuhara; [[https://www.creativeuncut.com/gallery-10/rs-illust-sakura_hinata_natsu.html there's even art of all three hanging out together]]), and Tiffany Lords and Hinata have made cameos in ''V''. And if that wasn't enough, ''VideoGame/CaptainCommando'' exists TwentyMinutesIntoTheFuture of this SharedUniverse, as one of the playable characters, Sho ([[DubNameChange Ginzu]]), is the successor of the Bushinryu ninjutsu utilized by Guy, a connection that is reiterated when they team up in ''VideoGame/NamcoXCapcom''. The very first level happens to be a future (but still crime-ridden) Metro City, and players can find a bust of Haggar that awards 5000 points at certain points throughout the game.

* While ''VideoGame/Doom2016'' seemingly started a separate continuity à la ''VideoGame/Doom3'' while still making obligatory references, ''VideoGame/DoomEternal'' outright confirms that [[spoiler:the Doom Slayer is indeed ''the'' Doomguy from the classic games whose battle in Hell led him to the distant past]], creating a new timeline. At the same time ''VideoGame/Doom64'' is also welded into the main canon, despite it being made by Midway Games instead of id Software, as well as confirming the lore bits about the Slayer in ''VideoGame/QuakeChampions'' to be accurate, despite that game's LooseCanon approach. And if that's not enough, the presence of the lost city of Hebeth during the Mars Core mission heavily implies that [[spoiler: ''VideoGame/Doom3'' may have also occurred within the main timeline, albeit with a different protagonist than classic Doomguy.]]

** ''VideoGame/StreetFighterAlpha'' effectively combined the ''Street Fighter'' and ''VideoGame/FinalFight'' franchises into [[SharedUniverse one shared continuity]], by featuring Guy and Sodom from the first ''VideoGame/FinalFight'' as playable characters, followed by Rolento in ''Alpha 2'' and Cody in ''Alpha 3''.

** The Shadaloo Combat Research Institute profiles on the ''Street Fighter V Character Encyclopedia'' website has entries for characters from ''Capcom Fighting All-Stars'', ''Capcom Fighting Evolution'', ''Cannon Spike'', ''VideoGame/FinalFight'' and ''[[VideoGame/FinalFight Final Fight: Streetwise]]'', ''VideoGame/MarvelVsCapcom'', ''Pirate Ship Higemaru'', ''VideoGame/SaturdayNightSlamMasters'', ''VideoGame/StreetFighterEX'' and ''VideoGame/FightingEXLayer'', ''Street Fighter II: The Interactive Movie'', the ''VideoGame/StreetFighterTheMovie'' game, the ''WesternAnimation/StreetFighter'' animated series, ''VideoGame/StreetFighterOnlineMouseGeneration'', and ''VideoGame/StreetFighter2010''. A handful of these profiles are stated to be non-canonical, however, including one (Ingrid) who had indeed appeared in a ''Street Fighter'' entry.
** As of ''Tekken 7'', the existence of Akuma in the latter, being relatively plot relevant in comparison to other characters, and an implied connection between the Satsui no Hadou and Devil Gene, ''Street Fighter'' is also canon to the ''Tekken'' universe (and, by extension, the ''Soul Series'', which is a distant prequel to ''Tekken'').

* [[VideoGame/CapcomVsWhatever Some of Capcom's more robust crossovers]], like ''VideoGame/TatsunokoVsCapcom'' and ''VideoGame/MarvelVsCapcom3'', imply that many a Capcom franchise share some implicit but mostly unexplored degree of connectivity (going beyond the SharedUniverse the ''Franchise/StreetFighter'' franchise is known to be part of). For example, [[VideoGame/{{Darkstalkers}} Morrigan]] in ''[=TvC=]'' expresses disappointment that VideoGame/ViewtifulJoe didn't live up to what she learned from Joe's rival Alastor. Alastor, as per the [=PS2=] version of ''Viewtiful Joe'', is the spirit of the sword Dante picks up in the original ''VideoGame/DevilMayCry'' and Dante's (admittedly non-canonical) story in ''Viewtiful Joe'' [[spoiler:has Mundus, the BigBad of the first ''[=DMC1=]'', as TheManBehindTheMan]]. Then, Dante and Joe are shown to be buddies/friendly rivals given their ''[=MvC3=]'' intro quotes for each other, which would be strange (seeing as they never actually met in ''Viewtiful Joe'') if not for the fact that Dante was a playable character in the PSP port of ''Viewtiful Joe: Red Hot Rumble''.

* Again, par for the course regarding ''VideoGame/SuperRobotWars'', due to their MegaCrossover nature, but the specific example goes to ''VideoGame/SuperRobotWarsOriginalGeneration'', having the unenviable task of integrating the countless OriginalGeneration stories from previous ''Super Robot Wars'' installments into a cohesive UltimateUniverse, often filling in the blanks left by licensed characters with its OriginalGeneration. For example, the "[[AMechByAnyOtherName Choukijin]]" from ''VideoGame/SuperRobotWarsAlpha'' were originally connected to the ''Anime/MazingerZ'' mythos; in ''Original Generation'', they were created to combat the [[EldritchAbomination Einsts]] from ''VideoGame/SuperRobotWarsCompact2''. A later ''Original Generation'' installment, including at least [[VideoGame/SuperRobotWarsZ one licensed saga]], places more emphasis on space-time dimensional elements, a handy way of working in anything that can't be shoehorned in thoroughly into main continuity, but also working around obstacles that might violate pre-established canonicity. From there, the ''VideoGame/EndlessFrontier'' games tie it to ''VideoGame/NamcoXCapcom'' and the ''VideoGame/{{Xenosaga}}'' series, then they all ended up in ''VideoGame/ProjectXZone''. ''2nd Original Generations'' and ''Moon Dwellers'' even made their preceding crossovers (''VideoGame/AnotherCenturysEpisode R'' and ''Project X Zone'')explicitly canon.

** When SNK made ''Art of Fighting 2'', they decided to officially make the ''VideoGame/ArtOfFighting'' series part of the same continuity as the ''VideoGame/FatalFury'' series. To explain why the ''Art of Fighting'' cast were not around during the events of the ''Fatal Fury'' games, they made the ''Art of Fighting'' series a {{prequel}} to the ''Fatal Fury'' series by setting it ten years before and putting a young Geese Howard as the TrueFinalBoss in ''Art of Fighting 2'' (back when he was still the police commissioner of South Town). When SNK later wanted to cross the ''Fatal Fury'' cast with the ''Art of Fighting'' cast in ''VideoGame/TheKingOfFighters'' games, they had to place the third series [[AlternateContinuity in a separate continuity]]. And from there, it starts getting ''really'' weird, with Ralf and Clark from ''VideoGame/IkariWarriors'' and Athena from ''VideoGame/PsychoSoldier'' (who is the descendant/ambiguously-the-reincarnation of the Athena from ''VideoGame/{{Athena}}'') appearing in ''VideoGame/TheKingOfFighters'' -- despite ''Psycho Soldier'' involving an invasion of monsters from beneath the earth that you'd kind of think would get mentioned at some point in ''KOF'' canonicity if it happened -- and then both Ralf and Clark and ''KOF'' original Leona appearing in ''VideoGame/MetalSlug 6'' and ''Metal Slug 7''. At this point, the only sane response to the SNK canon is to throw up your hands and shout "I don't know!"

** There's also ''VideoGame/NeoGeoBattleColiseum'', which adds some of the properties SNK acquired from buying [[Creator/{{ADK}} Alpha Denshi]] (namely ''VideoGame/AggressorsOfDarkKombat'' and ''VideoGame/WorldHeroes'' into the mix.

The latter, in particular, is also part of the Fatal Fury/Art of Fighting timeline in its original form, as is ''Buriki One''. Both series have had two GuestFighter entrants each in ''XI''.
** ''The King of Fighters XIV'' goes a step further by introducing the Another World Team, consisting of Nakoruru (of ''Samurai Shodown'' fame, last seen as a non-canon fighter in the UsefulNotes/GameBoy port of ''[='95=]''), Mui Mui (from the pachinko game ''Dragon Gal''), and Love Heart (from the pachinko game ''Sky Love''), who are drawn into the ''KOF'' world due to a dimensional rift. In short, the implication is that any of the SNK games that don't fit neatly into the ''KOF'' timeline, and even some of the ones that could, all exist as part of [[TheMultiverse a greater cosmology]]. There’s also ''Neo Geo Battle Coliseum'', which adds in some of the acquired Alpha Denshi characters into the mix.
* The ''VideoGame/FinalFantasy'' series is mostly a NonLinearSequel, but has a few counts of direct crossover. Some early examples are [[VideoGame/FinalFantasyV Gilgamesh]], who was banished to a world between universes and is the same person in most of his appearances. [[VideoGame/FinalFantasyVII Cloud]] later appeared as a guest character in ''VideoGame/FinalFantasyTactics'', via a machine that can reach across time and space. (The remastered version of ''Tactics'' for the PSP also adds [[VideoGame/FinalFantasyXII Balthier]] and [[VideoGame/FinalFantasyTacticsA2 Luso]].) Around the time ''VideoGame/DissidiaFinalFantasy'' appeared, games (especially mobile spinoffs) began suggesting that all the worlds of ''Final Fantasy'' are planets in numerous universes separated by the Void, which can be crossed on occasion.

** [[VideoGame/SuperSmashBrosForNintendo3DSAndWiiU The fourth game]] seems to pick up where both ''VideoGame/TheSubspaceEmissary'' (''[[VideoGame/SuperSmashBrosBrawl Brawl]]''[='=]s Story Mode) and ''VideoGame/KidIcarusUprising'' left off, as the various Palutena's Guidance conversations make reference to both games. [[spoiler:Dark Pit's conversation in particular shows that, following the events of ''Uprising'', he's decided to side with Viridi for reasons unknown.]]
** The Smashverse versions of Marth, Ike, Lucina and Robin are summonable in ''VideoGame/FireEmblemFates'', fittingly, via their Toys/{{amiibo}} (their real-life trophies). When talked to, they reflect on their experiences in the ''Smash'' universe, but Robin and Lucina also recognize characters from their [[VideoGame/FireEmblemAwakening game of origin]] that never appeared in ''Smash'', which leads to confusion between the characters due to the whole AlternateUniverse thing.

* Up until ''VideoGame/FireEmblemAwakening'', it was assumed that, barring remakes and direct sequels/prequels (and ''[[VideoGame/FireEmblemGaiden Gaiden]]'' which was a GaidenGame to ''[[VideoGame/FireEmblemShadowDragonAndTheBladeOfLight Shadow Dragon]]'' featuring a small number of its characters), all ''VideoGame/FireEmblem'' games were set in different universes and did not impact each other. [[note]]WordOfGod prior to ''Awakening'' did state that [[VideoGame/FireEmblemJugdral Jugdral]], the setting of ''[[VideoGame/FireEmblemGenealogyOfTheHolyWar Genealogy of the Holy War]]'' and ''[[VideoGame/FireEmblemThracia776 Thracia 776]]'', existed in the same world as Archanea and Valentia, confirming Naga to be the same character between all her appearances (or at least various incarnations of the same character).[[/note]] However, [=SpotPass=] and DLC content for ''Awakening'' used characters from previous ''Fire Emblem'' games--including ones that were not set in the [[VideoGame/FireEmblemAkaneia Archanea universe]]--and so to get around this, introduced a "gateway" (the Outrealm Gate) that allowed characters to travel between the different universes. This would imply that all of the worlds are connected, physically or otherwise, as part of some greater universe rather than separate, alternate worlds. As detailed above, ''VideoGame/FireEmblemFates'' even adds the ''VideoGame/SuperSmashBros'' universe to the mix.

** Outside of a multidimensional context, the universe of [[VideoGame/FireEmblemAkaneia Archanea]], [[VideoGame/FireEmblemGaiden Valentia]], and [[VideoGame/FireEmblemJugdral Jugdral]] was merged with that of [[VideoGame/FireEmblemTellius Tellius]].

* Bioware has confirmed that ''Franchise/DragonAge'' and ''Franchise/MassEffect'' take place in the same verse, and have started to offer proof of it in the games. Sharp-eyed players of ''VideoGame/DragonAgeInquisition'' may notice the head of a krogan mounted in the trophy hall at the Winter Palace. Additionally, in-game information files in one of the ''Mass Effect'' games show the world of Thedas, which is considered off-limits for landing parties due to the unpredictable phenomenon of the Blight. WordOfGod also confirms that Shepard, the hero of the original ''Mass Effect'' trilogy, is a direct descendant of the Inquisitor.

* Again, par for the course regarding ''VideoGame/SuperRobotWars'', due to their MegaCrossover nature, but the specific example goes to ''VideoGame/SuperRobotWarsOriginalGeneration'', having the unenviable task of integrating the countless OriginalGeneration stories from previous ''Super Robot Wars'' installments into a cohesive UltimateUniverse, often filling in the blanks left by licensed characters with its OriginalGeneration. For example, the "[[AMechByAnyOtherName Choukijin]]" from ''VideoGame/SuperRobotWarsAlpha'' were originally connected to the ''Anime/MazingerZ'' mythos; in ''Original Generation'', they were created to combat the [[EldritchAbomination Einsts]] from ''VideoGame/SuperRobotWarsCompact2''.

From there, the ''VideoGame/EndlessFrontier'' games tie it to ''VideoGame/NamcoXCapcom'' and the ''VideoGame/{{Xenosaga}}'' series, then they all ended up in ''VideoGame/ProjectXZone''.

In short, the implication is that any of the SNK games that don't fit neatly into the ''KOF'' timeline, and even some of the ones that could, all exist as part of [[TheMultiverse a greater cosmology]].

** ''VideoGame/StreetFighterAlpha'' effectively combined the ''Street Fighter'' and ''VideoGame/FinalFight'' franchises into [[SharedUniverse one shared continuity]], by featuring Guy and Sodom from the first ''VideoGame/FinalFight'' as playable characters, followed by Rolento in ''Alpha 2'' and Cody in ''Alpha 3''. ''Final Fight'' was originally intended to be a {{sequel}} to the [[VideoGame/StreetFighterI first]] ''Street Fighter'', and, most importantly, the two franchises had been already officially part of the same continuity since the console version of ''VideoGame/StreetFighterII'' first came out (proof of this was in the [[AllThereInTheManual instruction booklet]]). By extension, this also puts ''Street Fighter'' in the same universe as ''VideoGame/SaturdayNightSlamMasters'', since both that series and ''Final Fight'' feature the character of Mike Haggar. This is confirmed in ''VideoGame/StreetFighterIII'', where Hugo's ending has him about to enter into a tag-team match against two ''Slam Masters'' characters, who will vary depending on who his partner is (for instance, if Elena is chosen, she and Hugo will face off against Haggar and Black Widow). [[AllThereInTheManual Ancillary material]] released for ''VideoGame/StreetFighterV'' also mentions that Rainbow Mika's coach, Yoko, was forced to retire from wrestling after Black Widow injured her during a match. And if that wasn't enough, ''VideoGame/CaptainCommando'' exists TwentyMinutesIntoTheFuture of this SharedUniverse, as one of the playable characters, Sho ([[DubNameChange Ginzu]]), is the successor of the Bushinryu ninjutsu utilized by Guy, a connection that is reiterated when they team up in ''VideoGame/NamcoXCapcom''. The very first level happens to be a future (but still crime-ridden) Metro City, and players can find a bust of Haggar that awards 5000 points at certain points throughout the game.
