Ughhh, Assassin's Creed: Brotherhood missed your range by two measly months! Great game.
I am definitely looking forward to Gears of War 3 (coming out on September 20th) and The First Templar (release date is May 6th!!). The latter of those features the Templar knights similar to the ones I defeated in droves while playing AC: Brotherhood, although it's not made by Ubisoft.
I've been a real big fan of the new Mortal Kombat of late. Playing through Challenge Tower and beating the game with each character brings back old memories and new joys. One v. one is great too with buddies.
