@varwnos: you beated me on time, I was posting about Philippoi...

...
But I add something else, dunno if it could interest:
during the years, some cities changed names...:
Crenides -> Philippoi (renamed by... guess who?

)
Pagasai (Pagase?) -> Demetrias (and probably, earlier, Phtia ->Pagasai !!!)
Thermai (Therme?) -> Thessalonike
@MongoloidCow: good corrections. I'd write, IIRC
Olynthia -> Olynthos
Epidamnos: from Argolis to Epeiros (it's only similar to Epidauros

)
Stemykluros -> Stenyklaros (Messenia)
Lechtaion (Korinthos) -> Lechaion
Zaretha (Euboia) -> Zarethra
others maybe will come, in the meanwhile I've a suggestion: put together in one civ
Mikenai&Argos ... Peloponnesos will "breath" a little more, and it isn't so anti-historical... (Diomedes wasn't at same level of Agamemnon, for importance...).
