I'm going for a domination win on a large map right now. Let's just say it's very tedious. I have both Longevity and The Internet, and I'm only gaining about 1% on pop and land each turn. After a long war with the Aztecs where I convinced Monty to give me all of his cities, maps, and gold in exchange for his life (picked up about 8 cities) and am hip-deep in it with Shaka.
The only conquest that I did was a small DyP map with four Civs. It still went to the end of the tech tree.
