Middle Earth: Shadow of Mordor
Picked this up for 17$ on Steam and i'm nearly already an hour into playing it. I've heard great things about this game so i'm happy I finally get to play it. It's worth the money I spent and it's probably worth the full retail price as well. The whole open world aspect is awesome, and the graphics mixed with the tight controls are also very nicely done. I see why this game did so well.
