Turn 80:
I have just become a republic this turn.
Before the revolution, i finished the pyramids.
St. Regis is still buidling the collosus for a golden age. this is expected in about 16 turns from now. Mauch Chunk is building the FP.
Niagara falls just completed its library before the revolution and now started working on another wonder. There are several early middle age wonders of interest: Leos, Bachs, sun tzu. So i may start another prebuild for a second wonder, the golden age will make it all possible.
The other low corrupt cities are just producing Libraries + Aquaduct + harbor. The high corrupt cities produce settlers and workers for a little piece of ICS land. Unfortunately, i am already paying upkeep for my workers.
QCS stats

All AA tech except Contruction and Map making in 1 turn.
Looking at my current science output, It should be an easy 4 turn research troughout the middle ages.
