In my experience, gamers tend to also be people who love to imbibe alcohol. And, of course, being the gamers they are, they love to mix the two together. Hence the popularity of drinking games. That Drinking Game (actual name of it, I'm not just trying to play the pronoun game) is a new one that's up on Kickstarter now.
It's a pretty simple game. The cards tell you exactly what you're supposed to do when you play them. They're all fairly simple, so as to facilitate continued playing as the players get more inebriated. They're fairly simple like telling people to drink, or engaging in some sort of dexterity feat (which, of course, gets tougher as you continue playing), or simply create new rules that you can decide when you play the card. When do you end? When the room spins, I guess.
The Kickstarter campaign's up and running now. It's about 1/3 of the way to their goal with still 22 days left.
