Strategos Total War

[Azathoth]

But...there aren't any Celts in that map. You've got Greek colonies like Syracuse, Italic natives, and not much else in Italy. Rome, Carthage, and the northern Black Sea aren't there either!

And there's also a problem with only giving the Achaemenids Anatolia - what about the rest of the empire, which includes Armenia, Assyria, Egypt, Greater Iran, Bactria, etc?

They'll just be pushovers otherwise, and it seems unlikely that the Achaemenid King wouldn't try to retake his lost provinces (or allow the title of satrap to become hereditary!).

It'll be like the Seleucids in vanilla RTW.
