It's either Mass Effect 3 or Sleeping Dogs for me.
Also played Max Payne 3, I Am Alive, Spec Ops: The Line, Alan Wake's American Nightmare, The Walking Dead, The Amazing Spider-Man. Still haven't finished D3 though.
Other upcoming games that could be my GOTY are Assassin's Creed III, Hitman: Absolution and Resident Evil 6.
Perhaps a bit early for a definite GOTY thread, but I am curious.
