My favorites so far:
Uncharted 2
Batman Arkham Asylum
Batman is awesome, atmosphere, gameplay, action, riddles, hidden stuff and everything just spot on. Amazing game and i can't wait to start playing Arkham City.
The combat system in Batman is so fucking awesome, it takes a while until you get it, but then it's great, long long combos and not the usual button hammering.
Uncharted is just fun, thrilling scenes in that, and especially if your a little sensitive of heights a lot of fun. It gets repetitive at some times though, and towards the end there's too many open shoot-out scenes for my liking, but otherwise a great game.
