Turn 345 win. (Almost was turn ~320, was missing one CS.)
Settled on coast between the two rivers. Mostly to maximise river tiles, and not walking too far from the salt knowing my borders will eventually cover it.
Early on the optimal strategy is clear. Since this is OCC instant razing of conquered cities (even capitols) means there is no science penalty from having puppets, and thus conquest can start early without taking a hit to tech (which will already be low from having a single city). However not having much IRL time for doing a full conquest run, i still went with the peaceful information era approach.
In short :
- Extremely bad luck with exploration. Kept stumbling on fleets of barbarian naval units that would kill my explorers instantly.

You can almost hear them go "here he is again leaving the continent! get him!"
- Went order for research from factories. Wondering what you all did.
- Culture from CS was crazy, never had so many policies in one game since the days culture victory was about maxing 5 policy trees.
- Would be interesting to hear what people think of the diploconquest approach vs keeping the AIs alive for a lot of RAs? I never paid much attention to how much of a boost a RA gives, but it seems a lot weaker than popping a great scientist, this is why i rarely think the money is worth it. (Correct me if i am wrong, i'd love to hear some pointers on this.) Mostly i would like to know how many RAs those 200+ win times did get.
Mistakes :
- Friend with everyone, but i made a big mistake by not actively pursuing research agreements. I only did 2-3 of them before turn 200 and that's only because the AI asked. At some point i had over 9000 gold (saving for insta buying science buildings and insta allying CS when i find them, but finding them was very slow), only then i started actively going after RAs but it was too late for it to have an impact on win time.
- Didn't actively go after resources asked for we love the king day. Got 2 of them then stopped paying attention and went on a next turn frenzy for ending as my plan was already fleshed out.
- Forgot to optimise rationalism finisher, again.
I had the palace, world religion, and world ideology, so i only needed 14 city states. However when the world leader vote popped i only had 13, and was about to find the 14th city state on the next turn. I had completely missed those islands south of rome with the 3 city states, had explored the whole map but that small patch of the map (assumed i would find an extra one on the other continent so a lot of my explorers were around there). Bad luck i guess, could have easily been 320 turns win.

This was my first OCC ever, got the achievement.

And I do like these challenging maps, adapting to different situations keeps the game fun, sometimes bringing specific aspects of the game / strategies to light.
