I finally made it to this spoiler. At this rate, I'm not going to be able to submit. I've already given up my spaceship plans in favor of the faster diplo win.
Celts eliminated by me just after QSC. They had the GLibrary instead of pyramids.

Research was shut off until Education (Got gunpower from it first.

)
Hand built GLighthouse and used it to make contact and be the tech broker all the way through Astronomy.
Hand built FP right next to Sogut, planning on getting a leader from Celts or Carthage to move my palace.
Celts fell too quickly, even though I tried to milk it a little, war weariness forced me to end their existance without a palace jumper.
Made a big mistake declaring on Carthage, trying to take the oracle from Carthage. After losing a ton of knights to bad RNG and stupid attack strategies that left exposed knights in the open, I settled with two captured cities nearer my core. Pulling Rome in forced me to wait 20 turns, suffering more losses. But at least the 800lb gorilla didn't declare on me. Still no leaders.
As soon as I connected saltpeter and upgraded my few spears, I traded my only salt to Rome. I think that's why they never attacked me, even with no defenders in my cities. Some rounds, they were paying me >100gpt for saltpeter too.
I've been selling techs to the point that the AI are one tech behind me but can't research fast because I'm taking all their income in gpt payments. I'm not winning any medals for this game!
All in all, it started with a bad QSC, a worse middle age and, although I should win, it won't be a very satisfing victory. (That's if I finish before the 31st.)
