I just recently beat Portal 2, traded it in and got L.A. Noire. I'm on the third disk of Noire. I think I'll trade it in when NCAA 12 comes out.
Dragon Age 2--third playthrough as a mage, one 'cheevo away from getting a perfect on the game. Very tedious, though I'm having fun going through being a hypocrite.
Battlefield 2 BC: On level 22 after getting the game a couple of months ago, have all but two weapons unlocked, and the game is hella fun.
Red Dead Redemption: Picked it up for $20 and got the DLC when it was on sale via XBL. Going to go through that game after DA2 is finished (read: until DLC is available).
