Forest of Sin
I may have gone on a conquest spree in Civ 6 during my science-victory run. It started with civ 1 and 2 declaring war on me after civ 2 created the Great Library. I made peace with civ 1 relatively quickly, but waited until I had civ 2's capital and the GL before leaving him with one city left (I need to stop being merciful to the Ai). I was annoyed at myself for not finishing off 2 when 3 made Oxford University, and who I waited until I could do a religious liberation before declaring war on the. Again, left 3 with a small city before I made peace with them. Realizing 3 was still ahead in science to a degree, I decided to finish her off, but not before 2 and 4, the latter from another continent, declared war on me. I finished off 3, than 2 who was a shadow of himself at when war was declared, and also never saw 4 because of the ocean between us. I decided that 1 was now my biggest problem, and conquered him as well. Now I'm at peace with 4, and 5 left me alone. I may go after 4 if he starts making progress in the Space Race, though.
