Science victory turn 231
Technology: I went straight to optics, then mining and writing.
Build order: monument, worker, shrine, granary, trireme, trireme, settler, settler, great library. I was lucky compared to
@The_Black_Vegetable 's run, because great library finished turn 72.
War: with 2 triremes scouting the local area together I got tributes from Kathmandu (x2), Zanzibar, and Ormus, but not Buenos Aires on the hill. Kyzyl and Mogadishu netted two worker tributes and a regular worker steal from Kyzyl. I generally declared war as soon as I met a civ and took gold in peace deals, sometimes in exchange for luxuries. Much later I captured Lisbon with a few wonders.
Policies: full tradition, open patronage (98), rationalism (130 via Oracle) plus three policies, commerce to mercantilism, finish rationalism and freedom for ideology.
Religion: religious idols (first pantheon), then tithe and divine inspiration, then pagodas and reliquary.
Wonders: great library (72), ToA (88), NC (97), hanging gardens, and then spam as many as possible prioritizing CS quests.
Overall strategy: ensure safe sea trade routes, buy cargo ships or prioritize building them, bully all AI's early and use gold for growth, settle a 5th city late near great barrier reef and capture Lisbon about 15-20 turns prior to hitting plastics (187) to boost late game science. The Lake Victoria Island was a nice spot with tons of fish that I wish I had planned to settle earlier - it would have been a great city. Finally, managing great people generation to sequence the last one in Kyoto (had to de-select a few science slots for a few turns).
I really liked the idea of scouting with a swordsman to get an early samurai. I detoured to steel after education (124) instead, but this was a great idea!
