Never tried playing anything online on a console. It just seems so wrong to me, it's all about singleplayer fun at least in my eyes. Allthough I have played Halo with a couple of friends. Needless to say I sucked because whoever brought FPS games to consoles is a clot and should be brutally beaten.
Smackdown vs Raw 2010
Fifa 10
