I have yet to play Skyrim, but it is on my list. After reading so much about it here it sounds like it is spectacular. Still, I want to wait to see if the PS3 issues can be ironed out eventually.
For action/adventure games, I'll give the nod to Uncharted 3: Drake's Deception. Inventive puzzles (although not terribly hard) and stunningly recreated exotic locations make the game a joy to behold. Combat is sometimes frustratingly hard, but not impossible.
RPG I will say Dark Souls. Not your typical RPG. It is mysterious, claustrophobic, frustratingly hard, drips atmosphere, and is ultimately rewarding. This is the kind of game that gets under my skin.
