I loved this game. Beginning to end. Yes the story was a little shallow with an piss-puddle-thin antagonist, but man was it fun. The acting and the art direction made it totally worth enduring the juvenile "fuck-you" battles and penile comparisons.
Okay I'm not selling this game very well. It was great! Totally worth $35! GO GET IT!
The demo does a great job of selling the game as well. If you haven't tried that yet, start there.
