Just started up a test as the Persians. Some initial comments:
All leaders are called Leonidas on the chose civ screen.
In-game, the Babylonian leader's name is mispelt; should be "Nabonidus".
To the best of my knowledge, Median power did not extent far into eastern Iran. Bactria is well outside the Median orbit according to all maps I've got. Still, I realize it may be necessary or desireable from a gameplay POV.
I can't build new cities till well into the 2nd Era? Isn't that gonna mean that Persepolis gets founded pretty late?
