T309 SV.
I decided to go SV or DV, depending on what happens later.
Thanks to UA, I was able to sell basically all my luxuries for money. I managed to ally Zurich early which was very OP in this game (3 lux + extra happiness from allying), which helped a lot in early expansion. I stole one worker from england and luckily saved two from barb camps.
I kept England and Carthage at war, but Dido attacked me anyway around t110. I barely managed to defend my city (had ~5 composites at that time). Later (in industrial era) she attacked me again and after my feigned counterattack (with GG citadel by her city) she offered me peace+Utique (petra city with more pop than my cap).
I also managed to keep Ottomans and Portugal at war for nearly all the game and fortunately none of them destroyed another.
I was first to ideologies and got freedom. In the end Suleiman went autocracy, me and Venice freedom and everyone else went order. I had a lot of culture but still I was getting -12 from ideologies (up to -39 after Venice was destroyed near the end of game).
I was the last buffer against Portugal's tourism (thanks to great firewall I had more cpt than incoming tourism), but nobody else was close to any victory.
In the late game I was joint-attacked by England and Denmark, but thanks to my science lead I was able to defend quite easily. I feigned attack on England for ~250gpt peace. Then I took a city from Denmark and went for peace + reselling them this city for another 200gpt (not sure exactly). With this gpt I would be able to win DV at the next congress, but apparently SV was already closer and I had most parts bought.
