It's probably GOTY for me too. Either that or Risen 2, both of which are flawed in their own way. There were no games in 2012 that blew me away, such as Skyrim (2011) and Fallout: New Vegas (2010). Otherwise, the ending alone would've excluded ME3.

And no, I don't consider BG: EE a "new" game, so it's not a contestant.
