Yes! I did it! And I got there in the 18th century. This was my third attempt as the second one was lost to a blue screen of death (I stupidly didn't have the autosavefrequency set at 1), but that game wasn't going that well anyway.
Most of my strategy came from this thread, so a huge thanks to everyone who contributed. I regenerated for a while and got a start with good food, some hills and commerce resources. The catch was that many of these were calendar resources, but I decided to go with it anyway.
I did the raging barbs + great wall thing and I must say it works really well. Enjoy those barb axemen, guys! I'll just build some infrastructure here while running pacifism. The settled great spy also helped a lot with early espionage.
I also manipulated the starting locations of other civs using the knowledge from this thread (something I didn't even pay attention to on my first attempt). I set it up so that Joao, Cathy, Monty and Toku spawned in the north (two REXers vs. the trouble maker and the isolationist) and me, Wang, Brennus and Gandhi (filler civ) in the south.
Gandhi only got to live until ~1000 BC before I rushed him. Wang was almost killed by barbs (how a protective civ gets into barb trouble is something I'll never understand
), but I let him live and that turned out to be a good decision. I found out the entire world was buddhist, except WK (who was more like a city-state than an actual civ) was hindu.
My strategy was set there and then: Make friends with the AIs, get to Mass Media, build UN in a border city, gift it to WK and cruise to victory. I did divert from the MM beeline a little:
- I grabbed the late religions (Christianity, Taoism and Islam) just so that the AIs don't get them and break the buddhist harmony by converting. Philo is required for lib and theology speeds up paper, so you might as well take them. Divine right is a dead end tech, so maybe I would've done well without it. It's a good tech to trade around, though, as it doesn't really help the AI.
- Liberalism, obviously. The AI's tech rate was so abysmal that I deliberately held it back and eventually took Mass Media out of it in the 1600s! My heart skipped a beat when I saw Cathy running free religion (What! I checked the tech screen a turn ago and she was nowhere close!
), but then I realized she'd just built the Shwedagon Paya.
- Banking, to be able to run mercantilism (Toku's favourite civic). I also got a great merchant shortly afterwards, so I bulbed Economics.
I had avoided gunpowder, so I was able to double-bulb most of electricity with great scientists. When I gifted the UN to Korea, Brennus had actually the most pop and got me sweating for a while. Thankfully, biology + farm spamming + junk cities on cultural borders made me eligible again.
Here's a screenshot from the end, if someone's interested:
