I kind of avoided this one ideologically, but it works really well on higher levels when you are looking for a straight military victory. I turned off everything except dominance (i.e. the 66% of land surface) victory condition. I went from despot to monarchy to democracy to communism as my empire got more and more spread out -- no way are two administrative centers enough. A brief stint in Democracy just didn't cut it -- I was getting overwhelmed by corruption, and of course every time I would attack someone to take more territory my population started ripping up the nice things they built. You can't take 66% of the land surface and not end up with a lot of cities spread out all over the place! It has been a challenge to stay up on tech, but I can usually extort tech in exchange for a peace treaty. Conscription benefits are great too -- you can crank population using irrigation and while it eventually catches up to you three new infantry per big city per turn goes a long way toward plugging gaps in the line and garrisoning captured cities. Nothing new here for more experienced players, but if you haven't tried it in a military victory game you are missing something big -- now can we call it something else? Communists in the real world didn't do so hot on the military front did they.
