Modern warfare 2 :). The first had great single player and very addicting multiplayer. cannot WAIT FOR THIS! pre ordered the Prestige edition :D.

Halo: ODST. i'm a fan of the halo series having everyone except for halo 2 (Beat it on co-op at a friends never had an orginal xbox.) and halo wars so i don't see why i wouldn't pick this one up.

Bioshock 2. I LOVED. the first bioshock.

Dragon age origins. After reading up a bit on this it seems really good and i'd like to pick it up :).
