Early game
I have used Snaaty excellent guide for this game. Key for fast expansion were fast Code of Law (via Oracle) for religion and courthouses and Monarchy for happiness.
Warrior was my main defense forse with few immortals for handling of barbs.
I got my first Great scientist in the city with the Oracle. I wanted GS instead of prophet.
Built Great library in my third city. Now, this is a funny story: After Great library it's National Epic ofc. NE came online 1 turn before my city was about to spawn its first great person. And it was Great Artist!
Consider the odds of that happening!
I was a bit upset but he was later stored for an Golden age. I recruited 2 more scientists and 1 spy to speed up. Curiously next great person was a Great spy with a 15% ods.
Damn.
Mid game
My initial tought was to race thorwards Lib but I saw that Taoism is undiscovered so I turned thorwards Optics and Astronomy. Then Liberalism (taking Nationalism) and then starts Persian GOLDEN AGE which is powered by:
3 great persons (2 artists and 1 great spy)
1 Taj Mahal
1 Mausoleum
36 turns of prosperity.
During that time I raced for Chemistry and pirates. Bulit bunch of them and molested most of the coastal cities. Income was tremendous. I had 90% science and positive income.
Late game
Rather boring turns. After I got Rocketry I have converted several cities for production centers with workshops replacing towns. Civic changes were in order too:
Women Suffrage, Free speech, Caste system, State property and Organized religion.
