I like that little map you have there. This project reminds me of the Hegemony campaign from PI - in fact I will let you use the Greek factions from PI to make this if you want because they would work really well on that map. The city-states in PI include Sparta, Athens, Corinth, Thespiae, Thebes, Eleia, and Arcadia. Let me know if you want to use anything from PI and I'll let you know who all to credit.
