I recommend Fallout 3 too. I haven't tried Vegas yet because I only recently got into 3, but there's just so much to do and explore. Otherwise, Uncharted 1 & 2, Heavy Rain, and LittleBigPlanet 2 are all superb games.

South Park has quite a few references. In the episode "The Ungroundable", all the kids are playing Call of Duty: World at War in computer class (a team death match in the castle map). They're also all playing World of Warcraft in the episode "Make Love Not Warcraft" and Cartmen mentions that he wants to play Grand Theft Auto: Chinatown Wars in an episode about debt, I don't remember the name of it though.
