No civ has researched
Sedentary Lifestyle. There was some guy, who has completed greatest work of his life called "Most advanced civilizations of the world". And my Babilonian civ was named most advanced. And I haven't even researched Tribalism. It's ~140000 BC in game.
It was such a good plan...
I've checked number of turns for Siam to finish building
Culture Neanderthal. When only 11 turns were left, I moved out my invasion force. 7 moves in forced march, then cancel forced march, then 3 moves to heal after crossing desert in forced march, then Siam completes Culture, then 2 turns to cross the border (war declared) and deploy in designated squares.
Such comprehensive plan. And such disappointment
