Then , as i read its not gonna be just a "fix" , but u will implement the mod with many more features..thats awsome!
Actually Pelloponesean War means Athens VS Sparta Alliances...Spartans asked some economic help from Persia , and thats how Persians are included..
The strange with this war was that Athens was incredibly strong in Navy , and Sparta in Infrantry , and thats why they couldnt organise a "proper" Great Battle , cause both were trying to bring each other on his "weak" spot...Finally Sparta , strenghtened his Navy with the help of some Persian gold , and thats how they crashed Athens..
But some years before we had the Greco-Persian wars which are MUCH more interesting , since they include Heroes like Miltiades , Leonidas , Themistokles etc...
Anyway in my opinion if u dont care too much for historical accuracy , but for many factions and tons of cities , i insist on adding factions like :
greek : Macedonians , Thessalians , Cretans , Troyans etc
non-greek: Persians , Romans , Illyrians etc
