I don't know what kind of influence could make the fact that the game is a 3 vs 3 game with characters that had TONS of animation frames
You know KOF12/13 characters have roughly the same amount of animation frames as the old KOF characters sprites do right? Roughly 500-600 frames. It was stated an interview way back about KOF12's sprites and animation process.
Street Fighter III Third Strike has over +1,200 frames of animation per character, Garou:Mark Of The Wolves about 800-1,000 per character. BlazBlue has about 900-ish to a 1,000 per character I think last I checked the sprite files.
Of course, KOF characters from the earlier installments had a ton of moves, close to a half dozen specials, multiple command normals, several supers per character, plus a number of intro and win poses. There were also a TON of unique "get hit" animations in KOF games, think of many of the different grapple moves and such, especially from Blue Mary. KOF13 condensed all that so instead of useless silly stuff like intro's, win poses, taunts, etc, you have the core moves for each character, and they are all animated delicately, while kept within a reasonable limit of overall animation frames per character.
