I'm a fan and definite studier of Greek mythology and history. The Athenians were intricate and innovative people. 'Basic' would be a serious understatement. If you want to go basic with the buildings, go with the Spartans. Don't forget their militaristic theme. If you want to go into much more detail and less buildings, I'd go with the people of Troy. If you want even more buildings but less detail, I'd go with the Byzantines (not really in Greek mythology, but meh).
More points :
Vanilla terrain
Not much terraforming work was put into this (or I can stand corrected that no terraforming work was done other than the dome)
Unfair Cornucopia
The Cornucopia is hilly on one side and considerably flat on the other sides
Buildings require more detail
More detail, or even the genie will never fulfil your wish of this being in the servers.
