T206 CV. Thanks to @Boyan_Sun for the idea of combining Pingala with the Oracle built outside of the capital, but the Apadana was gone by T60 and the Great Library was gone just as I finished Recorded History. Even so, Kongo has 4 extra slots, so it was all good. I ended up with 8 cities and was totally peaceful (except for capturing a free city with 2 warriors and an archer). I think having a research alliance instead of a cultural alliance would have served me better. The cultural alliance boosted my main competitor, while a research alliance would have enabled me to get to computers faster. The best thing about my game was having Babylon tucked neatly into my territory: science for great works of writing!
