* HilariousInHindsight:
** Apparently, the "Stylish costumes" for characters in ''All-Stars'' were scrapped because Creator/{{Capcom}} couldn't see some of the characters in the chosen outfits. This is before they signed off on Ryu's [[https://streetfighter.fandom.com/wiki/Alternate_Costumes/Street_Fighter_V?file=Ryu-B-Boy.jpeg#Ryu B-Boy Costume]] in ''[[VideoGame/StreetFighterV V]]'', and before ''Street Fighter: Duel'' gave everyone some [[https://streetfighter.fandom.com/wiki/Street_Fighter:_Duel?file=SFDuelPromotionalGroupPosterArt2.png exclusive new duds]].
** [[VideoGame/DevilMayCry Dante]] showing up to face Jedah in the latter's ending, since the two would end up fighting in the story of ''VideoGame/MarvelVsCapcomInfinite''.
** ''All-Stars'' was going to be primarily based off of the ''Franchise/StreetFighter''-''VideoGame/FinalFight'' SharedUniverse with characters from other Capcom properties such as ''VideoGame/{{Darkstalkers}}'', ''VideoGame/{{Strider}}'', and ''VideoGame/RivalSchools'' showing up as playable characters. Come ''VideoGame/StreetFighterV'', the latter two series [[CanonWelding officially]] became part of the ''Street Fighter'' canon: Season 2 would add Zeku, who's all but stated to be the founder of the Striders, and Season V would bring Akira Kazama into the fold, with her Story Mode confirming that Sakura's [[GuestFighter appearance]] in the first ''Rival Schools'' was canon.
* TheScrappy: Ingrid, who is widely disliked for being the face of a less-than-stellar fighting game, and for being an improbably powerful goddess with a bland schoolgirl design. By itself it would not be an issue, but [[VideoGame/StreetFighterAlpha her]] [[VideoGame/StreetFighterXTekken later]] [[VideoGame/ProjectXZone appearances]] -- the PSP port of ''Alpha 3'' in particular -- would have her getting pushed prominently while defeating up more powerful characters with poorly explained [[StoryBreakerPower Story-Breaker Powers]], which led to the fandom perceiving her as a CreatorsPet. To Capcom's credit, ''Project × Zone 2'' [[TakeThatScrappy does take several potshots at Ingrid]], either [[FourthWallObserver by means of]] [[VideoGame/NamcoXCapcom Xiaomu]] or [[SelfDeprecation Ingrid herself]], though for some it wasn't enough to undo the damage.
* ScrappyMechanic: It's a neat idea to have various characters from different franchises against each other, but Capcom also ported their mechanics over on a per-game basis. So the ''VideoGame/StreetFighterII'' characters are fundamentally crippled with their ''Super Turbo'' rules compared to the rest of the other cast members, who have numerous abilities like air guards, rolls or dashes, parries, Custom Combos, double meters and other things originating from their titles. The characters from ''VideoGame/RedEarth'' and ''VideoGame/{{Darkstalkers}}'' even had to get statistical buffs to equal up to the numerous ''Street Fighter'' carryovers. The mechanical clash resulted in some severely unbalanced play and tiers.
* SoOkayItsAverage: Those who didn't hate this game thought of it as this. There are certainly worse fighting games out there, but it isn't anything special, either.
* SuspiciouslySimilarSong:
** The New York stage music is a Music/{{Grandmaster Flash|AndTheFuriousFive}} homage.
** Ingrid's theme is noted to sound similar to Music/{{Iron Butterfly|Band}}'s "Music/InAGaddaDaVida".
* TheyWastedAPerfectlyGoodCharacter: The majority of the game's roster consists of four characters from each game represented and ''VideoGame/RedEarth'' just happens to have exactly four playable characters. [[SarcasmMode So it's only obvious to have two of its four reps be unplayable bosses who are not even remotely humanoid.]] While [[BeastMan Leo]] and [[{{Ninja}} Kenji]] made the cut, rather than being joined by their contemporaries, [[HotWitch Tessa]] and [[KickChick Mai-Ling]], the game instead replaces them with the monstrous Hydron and Hauzer. But don't worry, the girls still show up... as cameos in Leo's ending. Tessa's exclusion is even more of a glaring omission considering she was the only character of the cast to appear outside of ''Red Earth'' (and therefore its most recognizable character), being playable in ''VideoGame/SuperGemFighter'' and ''VideoGame/SNKVsCapcomSVCChaos'' -- the latter of which released a full year ''before'' this game.
* TheyWastedAPerfectlyGoodPlot: Well, more like they wasted a game concept, but the idea of a Capcom crossover fighting game that didn't involve [[VideoGame/MarvelVsCapcom Marvel]], [[VideoGame/SNKVsCapcom SNK]], or [[VideoGame/CapcomVs any other company]] and simply uses Capcom properties definitely deserved better.
