Well of course Halo, only the greatest game ever!
New Blackops II is pretty cool, only got about 1.5 hours in last night, only a 7 right now.
Also bought assassins creed, I never got fully in-depth in the first two AC games, so the 3rd one is pretty sweet. though I have heard some grumblings from buddies of mine that played all of the AC games and say this one is pretty similar and they were disappointed. 'Basically moving from point to point killing one guy and then the next, not a lot of other things going on', were the words of few. I like it as an amateur to the game.
