The answer is,

Batman: Arkham Asylum.

Good game so far. I also bought The Godfather II along with it. Those two games should keep my going for quite awhile

 Other good games this year I MIGHT be purchasing: God of War collection, Uncharted 2, Gran Turismo 5, Ratchet and Clank: A Crack in Time, Call of Duty: Modern Warfare 2 and Pro Evolution soccer 2010.Also anything else good that catches my eye, Batman for example I was never really anticipating, because well, those games don't usually turn out that good. That is all for now.
