Metzi,
Congratulations on your win!
I did the same thing in my Cultural game by hoping that the United Nations resolution on Free Religion would be adopted, and wasted a lot of turns waiting for the next opportunity to put the resolution again (and again) where it got defeated (repeatedly). I ended up having to go the espionage route and using the Influence Civics option, which in hindsight was the way it should have been done in the first place. It was this that held up victory for several dozen turns.
The big difference between my game and yours was that there was practically no warfare in my game, aside from Julius Caesar and Ramasses having the occasional skirmish that didnt lead to too much. I hid behind the protection of defensive pacts with Huayna Capac and Zara Yaqob with practically no army at all, and maintained good relations with pretty well everyone.
Due to the variant that Catherine shall give into all demands, I indeed spent a lot of turns in anarchy thanks to frequent demands for switch civics. I inadvertently broke the rule once when I rejected Julius Caesars request for the 5,000
that I was stockpiling, and ended up giving it to him the next turn when it dawned on me what Id done.
I picked up a few freebies; I got the Liberalism slingshot and took Nationalism, I got the free Great Artist out of Music, and I got a free Golden Age for the Guns not Butter quest (Golden Age of Muskets for having the Taj Mahal). I got the four World Wonders that I was after; Pyramids, Sistine, Parthenon, and Taj Mahal.
On the downside, I picked up a lot of Great Scientists, most of who were against the odds. Building The Great Library certainly didnt help however. I missed The Great Wall and The Statue of Liberty each by one turn. Another blunder, I founded Civilized Jewellers (consumes Gems, Silver, Gold, of which I had none other than through trade) that I got confused with Creative Constructions! As it happened, shortage of culture wasnt the cause of the wins delay, but the religious variant.
It was not until I flipped Salamanca that I had access to more than Christianity and Islam for a fair slab of the game. Aryan and Libyan were originally Barbarian cities, and these plus the six self-founded gave me nine cities in the end.
The posted game has just got the worlds religious status right (all under one religion or Free Religion
Ramesses just took up Free Religion), where Uppsala can use one of its three (!) sleeping Great Artists to create the win.
