Wow, there is quite the run of bad luck going with this game!
I think my game was one of my better efforts. Domination in 1570.
I started out focused on grabbing land to get the edge over my peace-buddies. It took me 30 or 40 turns to realize that the Germans were hostile. Didn't hurt me too much in the long run, but I probably could've gotten that treasure trove of Gems earlier if I had paid more attention.
I would've thought the tech trading would make all the peaceniks powerful. However, in my game, the Greeks got swarmed by barbs and I didn't even make contact with them. Willem, Boudica, and I did some trading and it certainly helped me, but Willem was struggling. Right as I finished off Bismarck, he was losing cities to the Russians on one side and the Spanish on the other. I stepped in and beat up the Russians, but he was still struggling with Spain. There wasn't much sign of activity on the eastern front, so I marched northwest across Dutch land, liberated a few cities and then took on the Spanish. I was really cranking out the macemen and elephants at that point, so I had a 2nd force come around the bay, and a 3rd force transported by 2 galleys.
Once Spain was crushed, it was all downhill from there. I mostly focused on Knights and then Musketeers so that I could move them more quickly to the front. I rolled through Caesar with the only surprise being Boudica attacking on the opposite front and taking one of his cities. At the same time, I was moving through the outer cities of Persia, which was the most successful of the warmongers. I started a golden age to help me crank up culture and get those last few percentiles of land, but it was kind of a waste. I won on the next turn.
