Halo Reach, and it's bad for my health. I'm still screwing around with my comp so I can't play anything on it yet, and as far as the 360 goes there's nothing recent on there that even remotely interests me besides Reach (Blops can go to hell for all I care). Even so, the game is pretty stupid, my last match had 2 people quit in the first minute, leaving a 2v4 and getting sworded to the face/rocketed and teabagged. Honestly, the amount of people in that game who think they're hot shit because they can crouch camp is ridiculous. Still, I'd rather play that than FAMAS FAMAS FAMAS RCXD CHOPPER GUNNER FAMAS. I'd very much like to get into BC2, but I don't have enough people to team up with.
As far as good games go, Planescape Torment on my laptop. Good times, and a swift change of pace from all those damn kids getting on my lawn. I should probably get around to getting Arcanum as well, I've seen quite a few copies in teh gaem store sitting around.
