Games recently completed:
Mass Effect 2 -- I wish the main game had had more of the variety found in the DLC
Portal 2 -- a couple of the co-op trophies were tough, but I got the platinum!
Dead Space: Extraction -- I recently picked up the Sharpshooter as part of the SOCOM 4 bundle, and figured I'd try it on a rail shooter first; I had finished Dead Space 2 earlier, and this came on the disc
L.A. Noire -- Just a dozen vehicles to unlock, and I'll have the platinum
more LittleBigPlanet 2 -- I drifted away from this when PSN went down (I'd finished the single player), but definitely plan to get back into it, especially with the upcoming Move pack
Back to the Future episodes 2, 3, 4 -- my affection for the movies made me enjoy the first episode a lot
I also have Fallout New Vegas, Resonance of Fate, R.U.S.E., Killzone 3, and a bunch of PSN titles waiting for me. Not sure which I'll try next.
