Last little while I've been trying to improve my fastest science victory. Without much luck rolling a perfect map, I elected to play the DCL that had the fastest SVs. I replayed this a lot, eventually electing for a 5-city Tradition game - 4 city NC and 5th city shortly after Astronomy (T105, so settled around T110). The 5th city got me a luxury for WLTKD in capital; I grew it to 25 pop, getting 220 beakers.
City Populations: 54, 23, 27, 29 (Mountain), 25 (5th city, had 2 cargo ships running to it for a while). The 5th city meant less food caravans to the previous expos. I had saved up enough gold to kick-start it with a Monument, Granary, Aqueduct, and Workshop, along with a couple tile purchases.
Religion
Desert Folklore
Tithe, Religious Community, Swords into Plowshares, Reliquary (50 faith each time a great person is expended).
I produced 1 missionary, spreading to 2 expos, and 1 prophet which I planted. AI converted my expos dozens of times; I had to surround my capital to keep their prophets at bay.
Tithe was bringing in a whopping 17gpt at the end. I realize the Religion aspect could have been done quite differently. My main goal here was to have 2,500 or even 3,500 faith for 2 GS and perhaps a GE at the end. I was 1 turn away from 3,500 and could have used the final 1,000 to GE Sydney Opera House if I needed help finishing Rationalism.
Social Policies
Full Tradition
2 into Commerce
4 into Rationalism (Secularism + Free Through)
Mercantilism (Commerce) just before researching Plastics
Universal Suffrage (Freedom tier 2)
I think next I went 5th Rationalism policy, then 3 in Patronage to grab a late Scholasticism, then finish up core 6 in Freedom so I could buy spaceship parts and finish Rationalism to grab Nanotechnology
*trading gpt for gold helped me ally all Cultural CS for the final 9-10 turns of the Worlds Fair bonus (maximizing my use of 3 Great Writers on final bonus turn) and keep them for the remainder of the game, which is what led me to go 3 deep into Patronage
RAs
None. Didn't feel like I had extra gold until near the end.
Tech Order
Took Philosophy and built NC before Currency/Petra.
T86 Education (previous attempts were 88-93, but this time I had 9bpt of TR incoming), dipped down for Iron Working (Colossus), Metal Casting to start on workshops, then towards Astronomy
Printing Press ~T115, Scientific Theory T137, then Electricity and used Oxford on Radio
Plastics T163 using 1 GS bulb. I started trading gpt for lump sum gold every single turn leading up to this and bought 5/5 Labs immediately (Big Ben completed right on time); I kept trading gpt for lump gold pretty much every turn for the rest of the game, something I likely haven't done enough in the past.
After Plastics, got Fertilizer, then Penicillin, then onwards to Rocketry/Satellites. Not sure if including Penicillin before Rocketry makes any difference when going Freedom.
Beakers really took off as I started to produce research, build trading posts, and got Scholasticism (worth 96 at the end, which isn't that impressive).
I found it difficult to manage the GS bulbs and overflow, which I still haven't mastered. In the end, I had an extra GS sitting next to the capital and wasted a turn as I forgot to buy the 6th spaceship part immediately, but I'd replayed so much that I didn't want to replay any further just to shave off further turns.
Things I did not build:
I specifically chose not to build any Shrines, Temples, Amphitheatres Opera Houses, or Archaeologists. I also didn't build Circus Maximus, though I would have if needed.
War
I DOWed every AI in the early game for caravans, workers, 1 cargo ship, and a few tile pillages. Along with UA, this led to a lot of early gold. Scouts with Mt. Kil promotion can move onto hill in AI territory, pillage, and move back to 3rd ring in one turn, so I had to do that at least a few times.
Did not bribe the AI to DOW at all
Leveled up some units on nearby CS, generating GG that I used to grab more territory for capital
Attacked once by civ to the East; held them off long enough to make peace before they took a city. Peaceful game afterwards, only denounced once.
