Either Gears of War or Bioshock. Gears of War was the first game of this generation that truly felt like a next gen game. The graphics at the time blew everything else away and it shaped online co-op for this gen as well. Bioshock because of the way it changed how a games story is told and Rapture is the one of the best game worlds to be created.
