Sometimes, I get tired of conquering the world and all...maybe play as a weak but famous faction struggling for its bare existence among surrounding super powers is interesting too, at least for a change.

To be honest, I always want to play as a single Greek city states, such as Athens, Sparta, Corinth, etc.
For example I wish we could get Corinth as a faction starting as Macedonian protectorate...don't know if EB have some plan of province campaign.
