The Inca DCL was my first ever Deity win. This is now my second (note that I took a Civ hiatus in the meantime, so I wasn't trying that hard
). I did manage to maintain a better lead for longer, though, and would've won way sooner if I had pushed for diplomacy, but I insisted on Science (my first-ever Freedom/Science win, too. I usually go Order for Science).
The Aztecs are still amazing on Deity. I know this map had a crazy good lake, but the 15% food when near a river is all it takes to have a big city.
I wanted to have a few wars to fuel my culture, but my neighbours were super friendly, and I'm not going to start a needless war. These "opponents" were actually really helpful, the only hostiles being Babylon and Poland (and we managed to embargo both at the same conference!).
I made plenty of mistakes, though. I didn't plant any academies, for example, since my first GS appeared near Turn 160. I miscalculated both how much they would yield over time, and when the game would end. I also refused many Research Agreements for similar reasons. Oh, well, it's always a learning process.
Tried to go for a religion, but everyone in this game went Piety, apparently. Still got enough religion to buy a few religious buildings and two GSes, though.
By the end of the game, I had policies to spare, I went for Mercantilism and Scholasticism. The latter provided a really good boost, especially for me, who likes to play CS-focused games.
I managed to build quite a few wonders, too. Forbidden Palace was vital to control the WC, but I also managed things like Neuschwanstein, Broadway and CN Tower. Those were some very good city spots.
