Portal 2 - which was good
Skyrim - some parts I liked, some I didn't
AvP (2010) - eh, it was ok. Liked the Marine and Alien levels, but oh boy, did I ever not like the Predator controls in this one. The first two Pred levels were almost impossible, because all you got are your claws (they suck) and your shoulder gun (which sucks, as well)....then they give you the disc and the combi stick and suddenly everything is easy. WTH, developers?!
