It would be very interesting to have a political simulator where the internal population of the country is divided into factions, ethnic groups, and subcultures that differ on one of several dozen identity dimensions, and your goal is to lead the country and hold it together.  If you screw up and deviate too farm from the centerline, either an opponent leader takes over and you have to rebuild your powerbase, or the country splits up in civil war.   If it does split up and enter civil war, then the geography becomes very important and you need to hold territories (and their inhabitants) containing military bases, industrial production, and natural resources.
