babylon: 1892 warlord
one 20,000 citie but i only built 2 cities in the entire game since i wanted to make it a fast game...
Persian: 1892 AD too
This game was initially going to be a spacerace victory but i changed my mind and started constructing cultural building in the 1700, so i probably could have finished a lot earlier if i had started before.
Current game: 1335 AD warlord 30 turn before cultural victori.
I rarely finish game with cultural victories
