I had significantly more of everything than the AI, including cities, units, money. I'm on turn 300 or so, and every turn takes about 4 minutes, but if I'd realized how much tourism I was producing from historic events and had taken dictatorship of the proletariat instead of the one that lets you rush spaceship parts with engineers, I'd be finished. The tourism is almost entirely from having 400 faith a turn and automatically buying a great person every 5 turns, in addition to the ones I am naturally spitting out.
