I'll go with 20 civs. Wasn't that how many we had in Civ V?
Arabia:
No idea.
America:
Theodore Roosevelt. I'd go with Lincoln, but Teddy was on the trailer, so...
Aztecs:
Montezuma.
Babylon:
Hammurabi.
Brazil:
I don't really think Brazil will be in the Vanilla, but I'd love it to be. Lead by Getúlio Vargas, of course.
China:
Qin Shihuan. I hope it'll be Mao, but I don't think they'll do that.
England:
Either Churchill or Victoria. I'd be disappointed to see Elizabeth again.
Egypt:
No idea. Cleopatra, maybe?
France:
I wish for Joan D'Arc, but I think they'll go either with Napoleon or Louis XIV/XVI
Germany:
Wilhem II.
Greece:
Pericles, maybe?
India:
Gandhi, of course. Can't have a Civ without him.
Japan:
No idea who'd lead it.
Ottomans:
No idea.
Persia:
Uh... Xerxes?
Poland:
No idea.
Portugal:
D. Sebastian, of course.
Rome:
We had Augustus on V, so I guess it'll be Julius.
Russia:
LENIN, PLEASE. Or Stalin. If they're not gonna go communist, Ivan IV.
Zulus:
No idea.
