Dwarf Fortress

The other day, I read a post from AttacksofOpportunity in my feed reader, where he talked about Dwarf Fortress. I followed the link, read the review, and downloaded the (free) game. I spent a few minutes playing with it, in the way that a child plays with something that it does not really understand, comprehend, or know what to do with. I read a little on the wiki, and soon, actually got a working Dwarf Fortress going. It's ugly, and the menus alone present a learning curve, but ho-ly cow, I'm so hooked. I've managed to stay up late two nights in a row playing with it. Think "Dwarf Ant Hill (in ASCII)" and you've pretty much got it. I highly recommend giving it a shot.
