If anyone watched last night's Unprofessional Fridays (2/15/2013) and came here because of it, please play this game. It is completely awesome. Brad actually did a pretty poor job of showing off what makes the game so good, though. He should have played some beforehand to get past the intro and tutorials.
It's on 360 Games on Demand for $15, and it looks like a used copy is $10 at Gamestop/EB. I'm actually going to go buy another copy after thinking about the game last night, I gave a friend my old one forever ago.
