Culture win 227.
The main takeaway is 7 cities are way too many for a peaceful, freedom culture game: the increased cost in national wonders was not negligible, the extra science is not needed at all (I got Internet with an extra Scientist to sparse before I got half my artifacts), and the tourism from the last cities is not worth it.
Like my two worse cities, combined, make up 5.5% of my tourism output, which is laughable: not worth having to build 4 extra Archeologist who have to travel half the map to find dig sites.
Even the extra faith from having more cities was a non factor: I bought 2 Engis (the 2nd for CN Tower, absolutely a dumb idea, and it felt right in the moment only because I had many cities), but I would not have had enough for 2 musicians (imho the 1st Engi is a must).
Certainly I could have optimized better: I spent a ton of money to buy better farms that weren't better enough (like +1 after Fertilizer, which I got after Radio & Factories because it was well worth it here), I failed to time the 4th Musician and got it with 4500 power instead of like 8000, I certainly mismanaged the Science game, and somehow I got not one, but two extra Artists...at this point I should have built Louvre for sure.
A breakdown after turn 100:
T106 I lost a late Oracle attempt by 2 turns...not the end of the world, but it stinks
T118 I got a late Hagia Sophia to enhance, which was not necessary, but good (Temple happiness + Rel. Texts, buildings were all gone)
T122 Machu Picchu in Machu (NICE!)
I had no money to buy Unis, I got the last on T129 (quite late)
I was randomly attacked by America T135, and I had to build some defenses -> peaced T150 losing like 2 Pikes...at least I got a General out of it, which got me an out of range Gold (=7 gpt)
T144 Sistine, also quite late (I went Astronomy first)
T146 opened Rationalism after 2 fillers into Aesthetics, super late and I felt it, then Secularism T163
T156 Pisa, got an Engi which I used on Globe (not sure it was worth it, saving it for Broadway/Eiffel or even Uffizi/Louvre might have been better)
T165 I got Scientific Theory, but again basically I had no money to buy Schools so I completed the last one T178 (uber late)
T174 got Freedom via Oxford -> Radio
at this point tech path was Factories -> Fertilizer (very good here) -> Archeo -> Labs -> Internet (-> Airports)
T178 I rushed Eiffel with a faith engi, knowing I'd 100% get Broadway (which I got T200)
nobdy was willing to put hammers into WF, so I halted it as well to build Factories (got all of them T195), and finally won it T196.
Then I started spamming Archeos (20 needed for 15 artifacts and 5 Landmarks)
I bulbed Plastics T202, and bought 2 Labs immediately, then 3 more as soon as I had the cash
T211 SoL
T216 Internet (with a Scientist to sparse, womething went wrong...)
T216 rushed CN Tower with a 2nd faith engi (bad move)
T223 NVCenter, two turns too late because I forgot to start it lol
I bought 5 Airports as well.
I also forgot I had to send trade routes to people (no comment...), so I sent only 3 and I could reach Brazil, which was the culture "runaway"
aaand I also forgot to send Diplomats (I'm so dumb lmao), thankfully Brazil has Freedom as well so it didn't really matter.
All things considered, sub T220 was possible I think.
Mandatory tourism report:
It was a very fun game, the map was incredible and made the Incas really shine, bravo!
PS: culture is so much less stressful on Immortal with respect to Deity!
