Remember Civilization? Well it's back...in Pog form! I mean Mac form!
If you don't remember Civilization, well, you mustn't be a computer geek, and that's OK. But it'll take you a while to learn how to play FreeCiv, so check out some of the tutorials here. Just don't expect any cute girls to be impressed with your new found empire-building prowess. Trust me. They won't be. I know.

Was that a Simpsons reference? When did that stop being funny, 1997? Give me the download!
