Kinda Repetetive, God Help you on the PS2 Market.
Even if its completely different, and all the stuff you keep saying about 3D and new levels, the main point is , is that its just pretty similar to most other things Like Streets of rage, or side shooters, and thats something thats been there and done that territory.
As for PS2 And Gamecube, etc versions of it, i just hope to god you add something original in there, because the market for PS2 game sis focused on Graphics, then innovation, and if this was anything to judge the main thing by, then you're gonna have a very tough time competing with the main market of games that are put out there, because to me, this just looks like a already tried idea with just a few things which seem "cool" the first few times tacked onto it.
But, good luck, and shows you have some balls if you're actually gonna sell it.
