Viking: Battle for Asgard (360) - I picked this up used at GameStop for about $6.99. There were multiple copies on the shelf, and at first glance I thought it was gonna be a stinker. I was so wrong! It's a great action, hack 'n slash game, and took me completely by surprise. The in-game world is beautiful and the battles are epic. I found the final boss fight to be incredibly difficult, though, and have yet to finish it for that reason.
