Do you like losing most of the weekend on a surprisingly great game? If so you should check it out. If not RUN AWAY! Seriously, I grabbed it Friday night and played it on Saturday and just lost the day. Really fun, seemly simple, but great depth. I have one game with about 15 HOURS in it and I'm about 2/3 of the way through the tech tree. I got it on Steam for under $8.
