Why are the Celts even mentioned? All of your minor civs are relative to the region except the Celts. They were no where near the Greeks at the time. Various Germanic tribes were much closer as well as the Minons, the Hittites, and the Phoenicians.
I agree with some of the above statements that this is a great idea but with some big problems. You have taken out the major civs of the era (Athens, Sparta, and Thebes) and on top of that, I can't see how any of the various Greek civs would play or look any different from each other. It would be just like playing a game of Empire Earth set in the Ancient Age. Everyone would look the same and play the same. I would rather see ES remake AOE with the new techs they have developed over time. Sorry.
