So, Oblivion bored you, and you are not into Motorstorm or Resistance (by FAR the best game out right now, simply for the online battles!). I am serious, if you haven't played Resistance give it a shot before you dismiss such an awesome game. It certainly blows Rainbow Six out of the water.

I do not know what else to tell you. Try Ninja Gaiden Sigma, it is a solid title. be prepared for a challenge though!
