Spirit is a new drinking card game that's up on Kickstarter. They're looking to break one of the stigmas of drinking games in that they have designed the game to be deeply tactical. How you're supposed to retain your tactical thinking when you're half a bottle into the game, I don't exactly know. But seeing as I'm a teetotaler, and have never been drunk, I'll never quite get it.
In the game, you're looking to eliminate your opponent's "life shots" (by making them drink them, of course). You do this by playing cards from your hand. Cards you play have their own cost. This comes from casual drinking of your own drink, or possibly even one of your own "life shots." Last one left with shots (or possibly just still upright) is the winner.
The Kickstarter campaign's up and running now and is set to go for another 25 days.
