The winners are in for the 15th Annual Interactive Achievement Awards.

Skyrim, the fifth instalment of the Elder Scrolls series, took home five awards, including the coveted Game of the Year trophy. The next biggest winner was Uncharted 3, which took home three awards.

It seems the number in a game’s title had nothing to do with its number of wins, because Portal 2 took home three awards, despite having a 2 in its name.
