I'll write more about the game later - but for now, you simply need to know:
- it's cheap ($16 for the game, $24 for the "deluxe" version)
- it's cooperative (in other words, it's the players together against the game system)
- it plays well (I've played both solo and with two players with the print-n-play version... and so far we've only won one time)
- it's fast (30 minutes)
And, most importantly, you've only got 21 hours to jump on board.
What are you waiting for?
