My brother introduced me to this game called The Settlers of Catan. It's been around forever, but I'm just now getting into it. It's nerdtastically addictive, and best played with more than 2 people.

Basically, you have this randomized board, where you have to create settlements, cities, and roads based on a combination of luck and skill. Whoever manages to establish a stable enough settlement wins. There are buckets of rules, but they're all pretty intuitive, so you get the hang of it pretty quickly.

It's geekariffic. Believe you me.
