I've got a Mao Zedong scenario in mind: closed borders, agrarian / State Property civics, Chinese WoWs, forced Communism and Steel bee-lines, etc. type of thing, but need to think a bit more about the rules and the VC (UN Diplo or Domination?). Same 19th-20th Century leaders as the Stalin scenario, but random personalities. MadScientist has had a few Mao games with similar ideas about the variant.
These games were traditionally set at Prince level so that a wide audience could participate, but Monarch or Emperor would seem more appropriate these days. I'd probably do a World Builder as well as an Epic Monarch, the latter being for players to compare if they want.
