Contender, Domination 1802, 31K. I vacillated between Dom and Space, which probably cost a hundred years or more

. I killed Mansa and his Hinduism and Judaism early, made Suryavaman my permanent ally (got him to Friendly very quickly with my Confucianism, his favourite civic, and tech gifts), so he'd settle the whole continent for us. The other continent was all Buddhist, of course. I sucked up to Alexander and Augustus (the agressive AIs) while I got my armies into position, then decided to use Alex as my stalking horse. Lost a bunch of turns when Alex when WHEOOHRN as I was about to bribe him to attack the Chinese. His last war was against Egypt, so I repositioned to join the dogpile there... but it never happened. I ended up bribing him to war against Egypt once he came out of WHEOOHRN. Vassalized Ramesses, then Qin, then Augustus, using Alex's stack to capture cities once my stack had weakened them down. Alex was BFF with Mehmed, so I had to do the last push on my own... razed two cities on the way to Mehmed's capital, but he capitulated once he lost his stack that he'd sent to attack the Romans. In retrospect, the cities I let Alex capture didn't count towards my victory, since he was the only AI left who wasn't my vassal or PA. I would have had a higher score if I'd razed those cities. Once I'd vassalized the former owner, they'd rebuild the city (as Mehmed did with one of his cities I razed in the final push). If so, it would have been quicker still to just have ignored having a stalking horse and just run rampant on my own.
Had I stayed with Space, I'd planned to use Mining and Sushi to farm

out of my vassals to pass over to subsidize Suryavaman's vast empire. I had this plan in place, but by the time I had enough set up to make it seem worthwhile, I was close to a Dom victory. Shrug. Suryavaman himself was running State Property, of course, and that seemed a good enough idea to leave him there.
