Well with the Xbox that I have I can down load any new playstaion or xbox game that comes out. I also have all the old school games for the NES, SNES, genesis, Neo Geo, Jaguar, Turbo grafix 16 well lets just say all of them. I chipped my Xbox so I can have all games available. So when GT4 comes out I can download it to the Xbox hard drive. I say XBOX all the way. you cant do that on PS2.
