It was out of Batman Arkham City, Uncharted 3, Skyrim, Portal 2 and Skyward Sword.
I was rooting for Batman AC or Uncharted 3 to win but its no surprise at all that Skyrim won, congrats to it.
Personally i dont think Uncharted 3 had a chance at winning, the second one already won the award a couple years ago and these type of awards usually like to go with something different. Uncharted 3 was very similar to the second not really much better or worse.
Games like Batman, Skyrim etc however were huge improvements over the previous game and why they stood a better chance.
One of the favourites Gears of War 3 was never even nominated.
