Pergamon was built in 4 October 2003. At the time it 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 option called Rome Supplies Wheat).
Buildings count is as follows:
1328 Small Casas
9 Tents, used for labor access
285 Wheat farms
10 Temples: 4 Venus, 3 Cares, 3 Mercury
1999 total buildings which is maximum limit
Population is 90.484. The city is stable. I run the game for 5 years and haven't faced any problems. No festivals are needed and there were no festivals so far. Just closing the wrahts from Neptune and Mars is enough.
