I just bought a mutha f-ing 360

[VAMP]

Considering you have a PS3 I would suggest getting Oblivion on that, it runs a little bit better from what I've read everywhere. But, like everyone said, if I got a 360 I'd probably get Gears, Bioshock, Crackdown, Dead Rising, Mass Effect, and Saints Row. Can't think of anything else really.
