Slightly off topic but wanted to drop in my 2 cents. I've played the last 3 versions, 3-5 games each. The first few on emperor difficulty but at this point unless im testing something play immortal/deity. I mostly play on marathon but have done a few epic and standard as well.
I tried liberty and wide with Chinese at one point also getting a religion that included the 'cooperation' follower belief that gives +Xx to all yields when a city grows in pop. Between full liberty policy , cooperation, any number of possible founder beliefs although I tend to like the +faith and + culture when a great person is expended, and the opener for both asthetics ( + culture on Great people) and industrial (+gp on building)..... you get monstrous amounts of all resources whenever a city grows or builds something. These piggyback off each other especially with aqueducts and other keep food upon city growth buildings....where you finish a building you get a pop then you finish another building...basically one of the other or both every turn per city. Spamming new cities everywhere becomes worth it as they get you thousands of other resources and tens of thousands of gold as they grow. You get the produce any great people in industrial age and your funding your empire on cities growing buildings building and murdering your great people for projects.
I've tried this with some changes with Mayans. Byzantine. Carthage. China. Each do a something a little better but I've had 800,000 gp games (where im buying multiple building and units EVERY turn)with a score 4-5 the next deity AI.
