Read this all! [More cities in Greece]

[Hax]

There was more in the world than just Greece.

That's seriously all I'm going to say about it.

EDIT: Okay fine, I'll explain. Thebes had been completely razed by Alexander. It was rebuilt but lost its importance. I don't know that much about Argos, but I don't see any reason why Sparta can't fulfil the role Argos has. Ilis/Elis(?) was located too close to Korinthos, same goes for Pilos, Larissa is located too close to Demetrias, Thessalonika's role is fulfiled by Pella.

Before Greece, there are areas that deserve more cities, in my opinion; Mesapotamia and Iran, as well as Gandhara and Sicily.
