I've been playing doms3 for around six months on and off with a good friend of mine in the EA. Over the past few games he has been solidly kicking my *** as Mictlan despite my best efforts.  In order to improve my game I've begun writing a Doms3 Blog in order to force myself to think and learn more each turn I play.
I'm currently blogging my way through a very small single player game with three AIs.  You can follow along at
