My roommate has both systems, but I really want the game.
Does it control better on one system compared to the other?
Do you think the graphics will be better on PS3?
I say if you have both an XBOX 360 and a PS3 definitely get the game on the PS3 because the graphics will most likely look better and you get internet free on ps3 which enhances the game if that option is offered which it most likely is.
