Deh, a lot of your ideas are really dumb, but I like this one, a lot. I've been dying to do another strat battle, but at this rate that's probably a ways off. The idea of having equal AI raids to determine prosperity, but then just set the gold/population count back afterward sounds really good also. Might also get the diplomacy going full-swing as sides that have a vested interest in seeing a town within another faction's claim do poorly sign up for the raiders in bulk.
