@lifetap who has had trouble logging in lately mentioned my Large Sid Conquest game. Moonsinger's game took 12 fewer turns. But, she had 8 opponents, the minimum for a huge map. My
map had 11, the maximum for a large map. She gets to cavalry and railroads. In my game all AIs got crushed by riders and some trebuchets and cannons, and to my surprise no one even learned Military Tradition.
