Turn 111 Domination.
This ended up being super easy - I way overbuilt my military expecting resistance everywhere (I usually play Deity), and I way overbuilt infrastructure. Mostly I encountered Catapults, and many cities had no units at all. I only recall like 6 Archers, 4 Spears, 3 XBows, and 6 Crouching Tigers. Eventually every city had Walls, but by then I had Trebuchets and a Siege Tower, and finished with 4 Bombards, but only 2 fired a shot each in China as Bombards, lol. The early naval wars were challenging enough though.
I started by hard building Builders, as I needed to get Lux and Strategics up ASAP. I used early cash for Archers and tiles as I had plenty of Legions. Early cities had Holy Sites and Commercial Hubs or Harbors, with a few Campuses if no other good adjacency. I figured I would need as much cash as possible, and Work Ethic made many cities decent. I had Crusade but it made very little difference as Alex and Gorgo were pathetic, and I didn't get Missionaries down to Egypt in time. I eventually got Tithe, but by that point had quit caring about much of anything. I finished with 8.5k in the bank, the last purchases were Trebs to upgrade and sail to China.
Early I went at the Celts, then swung South into Spain. That army crossed into Africa and took Carthage. Many units were left on Barbs. Some of them and new recruits and a decent navy went to Egypt and eventually Tyre around t108.
In the East, I founded a city on each side of Mediolanum to keep it from flipping. Took out Alex and Gorgo, then Constantinople with 3 Caravels and Men at Arms and some horsies. Started to head towards Tyre, but Egypt was melting so fast I swung most towards China.
Every Barb Outpost had 2 units on it, I was farming 9, but had to abandon far SW Africa because a Legion and Archer weren't enough. I destroyed every naval one as I didn't need Barbs in the water.
I just randomly built XBows and Traders the last 30 turns or so... I ended with 12/15 Trade Routes, maybe 30 XBows, 6 Muskets, 18 Men at Arms, 2 Pikes, 8 Knights, 4 Coursers, 4 Bombards, 7 Caravel, and a couple Quads. I didn't lose a single unit, lol. Finished with 190 beakers, 152 culture, and 273 faith per turn. This was my first Dom victory in many years, since the Deity challenges for Civ V. In fact its only my 3rd finish in Civ VI because I find the sloggy grinds to the end so boring. I played this one out because I do enjoy Barb hunting and exploration, and the premise was interesting.
[edit - I have who knows how many mods running, so I wasn't sure what was my mods and what may have been the scenario. I had 3 movement for normal units, I assume that was from ARS Improved Movement mod. It really helps the AI move better. I would never have finished with normal movement - Zzzzzzzz. I also had Real Strategy which in theory made the game harder.]
