The first difference was that I tried to rush as many people as I could with war chariots, keeping Mansa alive because he could feed me techs, and Gandhi too because his territory was in an awkward position. That meant taking out everything to Washington and Pacal - this put me a bit behind in the short term due to strains on my economy, but Mutal and Washington (the city) were very important; the former built me GLH and the latter served as such a spectacular GP farm that I'm pretty sure I popped
five great scientists from there by the end of the game.
In addition, I basically blocked off about 50% of the land area in the world for myself to settle with just that, meaning I could backfill in peace and not spend a single hammer on actual military/conquest until the endgame, where I finished off Mansa for his rather juicy capital and city capture gold.
Tech-wise, it was an average dash to communism. Of particular note: I Oracled civil service about 1440BC, which saved me a massive amount of time and gave me a lot of extra commerce, because that was basically 1000 beakers for free (ind + marble = Oracle cheaper than a granary), and also buro is kind of broken in a capital with double gold. I also built Stonehenge since I would need border pops in 30-odd cities...and obelisks are not bad with rep, which I also got with mids. Oh yeah, I basically spammed all the wonders this game. Every single one - mids, oracle, henge, GLH, and colossus - were necessary to keep my economy afloat and functioning relatively well enough to get to state property.
Once I got that and switched into it, that was where the fun began. I spammed workshops and cities without abandon and basically coated the map in hammers. No corps needed, no courthouses, nothing fancy - just raw hammers and modifiers netting me over 6000 beakers/turn
without a golden age by the end of the game. Settling the outer islands would honestly have been a massive waste of time, so I didn't do that (and also I was just under 54%, so it would've put me over dom). After factories, which I got before electricity to savor Colossus for as long as possible, I found time to build Oxford in capital, and marked 15-16 cities or so for labs to build spaceship parts. I started a golden age around t139 and
spent the last 48 turns of the game until about the spaceship was done, in a golden age - chaining the first one with Taj, then a 2xGP one, and finally a 3xGP one. TGD was a steal, built in just 4 turns in my IW city. Tech order at the end was same as yours, except I went fusion before rocketry. This is to grab the GE which keeps the golden age chain unbroken until the end of the game - and you can actually complete the spaceship just 7 turns after finishing Apollo, as I did here, so a later Apollo completion date is no big deal.
A beautiful sight to see...almost perfectly lined up build queue near the end. Rough calculations meant I successfully finished every spaceship part in 7 turns or less. Though it was painful, I've learned you usually have to bulldoze towns/plantations/other improvements to get the raw hammers needed for such efficiency, at the end.

Details of the capital...Oxford + buro + gold = SCIENCE.
One of the best IW cities I've see...enough food to work all its tiles, and over 90 base hammers/turn even WITHOUT a golden age.
By far the best I've milked a GP farm; with NE I was regularly running up to 10 scientists with the food available, and getting over 50 GPP/turn for just over half the game. And, including the one from physics, I generated
ten great scientists everywhere over the course of the entire game!
I tried to fill out my continent as much as possible, but it was hard juggling with economy...after state property that I libbed t130 (375AD), all such concerns safely went out the window. This means that there were less than 60 turns (56, to be exact) from the time I barely got communism, to when I launched the spaceship (and, of course, got every single tech in between). On standard speed, state property is truly unbeatable in terms of speed.
Score, after I got greedy and built most of the late-game wonders/finished the tech tree just because I could.
Thanks for the map,
@jnebbe - it wasn't the
most OP I've seen, but it was up there. Had a lot of fun, and with just 3 turns left to spare until the t200 cutoff, it was actually quite a nailbiter! If I was financial, this would've been 10 turns faster. Perhaps the HoF should have a special "no financial" (and/or "no Inca") category just to give some of the other leaders a chance
