My pick would be Skyrim, as my character is already the max level after much, much training and boosting my skills, and I still have very much left to do in the game. The game pretty much just goes on and on forever so I will never be bored with it.
Skyrim Uncharted 3 Arkham City Skyward Sword Portal 2 Those are the only games I feel worthy of GOTY. Uncharted 3 is my GOTY, and it would've won much more GOTYs, if not for Skyrim, just like Uncharted 2 did in 2009.
Skyrim hands down for me, just like Oblivion before it. Huge beautiful scenery, limitless character and storyline possibilities. Amazing graphics and great replayability factor. Cant wait for the add ons.
Five years ago, The Elder Scrolls IV: Oblivion and The Legend of Zelda: Twilight Princess tied for GOTY 2006. In 2011, that tie remains. Your Friendly Neighborhood Satanist gives his GOTY 2011 award to both The Elder Scrolls V: Skyrim and The Legend of Zelda: Skyward Sword. They're just so good, and so equal in quality... it's too hard to call.
