There are several larger city-states - Sparta and Athens, obviously, but also Mycenae, Corinth (in a very strategic location - the Isthmus), Thrace, Argos, Pylos...the list goes on.

Athens and Sparta weren't always so strong - around 1300-1000 BC, Mycenae would have been the most powerful. And also, not all factions are equal in Total War - look at the difference between the Danes and the Germans, Byzantines or Almohads in MTW.

As for an Islamic one, some factions could include the Fatamids, Abbasids, Ayyubids, Seljuks, Egyptians etc.
Uuhhhh... Could it be some "Viking Invasion type" campaign for Rome Total War? I mean, if the purpose is the control of Greece!
