Demonstrated at PAX East this year was Zombie Dice, a quick, simple and sounds-like-fun game involving rolling dice for figurative brains. First to 13 points wins, but you only get your points if you roll less than three shotgun blasts before you declare your turn over.

PPS - But it would be better if the dice came up "brains" rather than "three".
