Skyrim wins 2011 VGA GOTY award and over a dozen more.

Although I sank about a 100 hours into Skyrim it's not my goty. It's certainly very addictive and definitely the best realized game world this year but apart from the awesome world the rest of the game is quite average.
Portal 2 and The Witcher 2 are both better imo.
