I still find it amazing how Sony didn't bother to make the PS5 controllers work on PS4, especially now that it is getting harder and harder to find official DS4 controllers in shops. I can get somewhat cheap controllers to use for single player games but I highly doubt they'll be any good for fighting games, its like they think that everyone has a PS5 at home by now even if they didn't make many of them or something.
but yeah now that the models are 3D sprites made to look 2D there's no excuse for lack of costumes, although considering most GG characters have rocked a similar look for 25 years i'm not sure if GG fans would even want multiple costumes, at least the old fans, im sure these new age kids would love to have bikini Dizzy and whatnot lol
