I didn't really plan to play this game as a science victory, probably wouldn't have picked Harald "Party Hard Rod" Hardrada for that, but when I saw this sweet start I had to give it a go:
5 unique luxes visible at the start, a 6th revealed when settler moved NE to settle.
I built one Spaceport, used Goddard, Korolev and Sagan. Didn't get any of the +100% Great People. I was done teching turn 182, so still some improvement to be made there. Could have started spamming district projects earlier. Didn't build any Research Labs at all.
Some benchmarks:
T70: 9 cities (settle 2 more next turn), 27/34 science/culture
T100: 15 cities, 121/102 science/culture. Since t70 I finished lots of Campuses and found and got suzerain status of Geneva. One Russian city had EC built, so I built Colosseum there. Chopped out Pyramids and Hanging Gardens as well while running the policy.
T116, 1AD: 15 cities, unlocked Enlightenment, 189/116 science/culture
The T100 and T116 numbers are the highest so far for me. Especially culture was way ahead of my previous best in a science victory. It was all thanks to Colosseum and GoToS, I never built any Theater Squares and hardly built any monuments either.
The slow GP generation without Divine Spark felt brutal in the early-mid game, probably because in my last science victory I had both Stockholm and Divine Spark. The fast overall tech pace getting rid of Medieval and Renaissance GP helped a lot. I got to Korolev long before Sagan even though I didn't build many IZ projects. Only built IZ projects in 2 cities that didn't have time to build Campus.
Apart from no Research Labs and no Theater Squares, I also built no Harbors and no Banks, only 2 markets for Guilds Eureka. Got Economics Eureka from Great Scientist. I built one neighborhood for Conservation inspiration in a city that didn't need it, but couldn't build Campus projects either. For the first time ever I built an Aqueduct! Peter had settled a city in an awesome area, except one tile off fresh water... In addition Peter had built Holy Site and Entertainment Complex there, so I needed it to grow to become useful.
I built one Encampment in the city I first thought would be my Spaceport city. At that time I was also thinking it would help me get the Civil Engineering inspiration, which I never got. In retrospect, maybe I should have teched Celestial Navigation and replaced one Commerce Hub with a Harbor. The Harbor would have been cheaper and it would have earned me the Civil Engineering inspiration, which is quite a lot of culture.
First war done with Archers, added 5 Horsemen for the next 2 wars. Didn't use any more advanced units than that.
The relevant city states in the game: Geneva, Seoul, Toronto and Hong Kong. I really missed Stockholm, otherwise I had everything I wanted. Kumasi was my closest neighbor. I left them alive since I thought they would help me a lot with culture, but I didn't need that and never bothered investing envoys into them. Should have killed them early.
What could improve on this? Well, obviously playing anyone but Harald. I didn't get any use at all out of his abilities, except some fast embarking/disembarking. Other than that, more cities! I had only 16 at the end. 20-25 is better. Less priority on early Commerce Hubs, took me very long to get campus+IZ in some cities. The map was great for early conquest, but almost completely lacked mountains in my part of the continent. More mountains would have helped. Also, checking the GP screen on T1 tells a lot. Expect to only get one Scientist/Merchant/Engineer of the first available era, the next probably skips 2 eras ahead. So if you want someone like Hypatia, she has to be there from the start. I had to recruit crap like the walls Engineer and the tile+60 gold Merchant. In another game you might have better luck.
