Get Call of Duty so I can destroy you and everyone you love, yes that means your mother, I want her to play so I can say "I HATE CASUALS!!!" while I shoot her with my Thompson and then proceed to teabag her.
Other then that, get World of Goo, Spider-Man Web of Shadows, Animal crossing, Zack & Wiki, Guitar Hero, No More Heroes, and Okami.
There's some other good ones but the above listed are must plays IMO.
