Ephesus was built on 18 October 2003. At the time was the largest population city built with the Windows version of the game where Rome does not supply wheat (in the map editor there is an option called Rome Supplies Wheat).
Number of buildings:
1358 Small Casas
13 Tents, used for labor access
10 Granaries
174 Wheat farms
80 Fishing Wharves
81 Fountains
19 Engineers
53 Prefectures
10 Theaters
10 Temples
10 Libraries
15 Reservoirs
120 Oracles
3 Clinics
3 Forums
1999 total buildings which is the maximum.
Population is 92.604 and the city is stable. I run the game for 5 years and haven't seen any devolving or other problems. No festivals are needed and none are used so far. There is no wrath from any god.
