1216 AD. I was all excited to get this early finish, but now I see walkerjks just beat me :-(
I wanted to try something different than everyone else, so I played
Qin
Lakes map
against Hattie, Cyrus, Asoka, Frederick
...yes, 4 opponents. I normally do 5 but tried 4 this time. I don't have any trouble keeping the peace, so I like to have more people to trade with. One drawback is that they are all so cramped for space that they don't tech very fast, so I have to give them techs so they will eventually discover something I want.
I was able to found 3 religions Confucian, Christian, Taoism, and Hindu spread to me later.
I was able to get 14 Great People. 12 Artists. (even without the Philosophical trait -- which may be overrated.) My best GP city could only manage 4 specialists...not much food around.
I put 11 of the great artists in one city! The other one was added as a super specialist early in the game to one of my culture cities. This way I could build zero cathedrals in this city and 4 in each of the two culture generator cities.
The two big culture cities were over 900 culture by the end. They both even finished the same year...1216. One city had 150,001 points.
I only played those 4 cities. My capitol had marble, no stone, and could not even trade for it. The stone was only about 10-12 tiles away from my capitol, but I could not settle way over there early on and expect to keep my tech up.
One mistake was I forgot to get Printing Press. I shoulda been able to trade Nationalism for it. I never considered getting banking.
I think if I had a better tech start and more food, this strategy could do even better. I didn't get Liberalism until around 500AD. I've heard some people stop researching before 200 AD. Are you getting Printing press before 200 AD too? I must be doing something different if that is true. My path through the tree seems very optimized. I've tried a few different ones. I usually use the Oracle to get Theology. Then either:
A. go Paper -> Edu -> Liberalism and can usually trade for Philosophy, Drama, music, etc.
B. this game I went Code of Laws, Philosophy, first, for the religions and the Caste System and then Paper, etc. I didn't get the free Music artist obviously.
