Does anyone know of a way to get an AI-vs-AI game going, with no human players and just watch it? I used to do that in the old SNES game "Romance of the Three Kingdoms" and let it run for a few days, looking over at the screen while I did other things.

I can't think of a way to do this in Civ4. Of course it'd also need to have full map visibility. It's also a fun way to get maps with country borders/etc to use as a background for an RPG world!

My best guess is that you could do it by using a savegame editor like this one (http://forums.civfanatics.com/showthread.php?t=153759), playing with the whole map revealed, of course.

I've always liked doing such things, but it's always frustrating when you cannot stop or pause things.
