Apparently there's actually a glitch with the 360 version that makes it look like PS2 graphics. That's what I've heard, anyway.
I believe it, because in the videos, there was little to no aliasing and good looking textures. I booted up my game and every edge looks pixalated, and the textures are horribly rendered messes. I really would love to get my money back, but [censored] walmart and their "open shrink wrap no return" policy wont let me.
