I am liking the look of this game but I am wondering what nations can you play as in this game? I assume Egypt, probably Greek. I am hoping any or all of the Aztecs, Incas amd Mayas. Having the 3 of those South/Central American civilisations would be "pushing it" as there would only be about 2 other civilisations.

There are currently ten playable nations (each with multiple starting leaders to choose from):

Aksum
Assyria
Babylonia
Carthage
Egypt
Greece
Hatti
Kush
Persia
Rome

The game does not cover the New World. Maybe in a future sequel?
