Round 4: United Nations and the hidden Apostolic Palace (960AD - - 1846AD T293)
Have you watched Sulla's AI survivor? I credit my diplomatic victory to the series.
I am getting ahead of myself. My situation in 960AD
I aimed for diplomatic because the circumstances allowed it, which I explain shortly. Even if I chose military I would still spam farms. The population was low enough that slavery will be the most efficient method of production for a long time.
For diplomatic, I had to predict where I got votes from. Rest of the world in 960AD.
Greece and Rome will become vassals and can be disregarded. They vote as their masters do.
Spain will capitulate to Gilgamesh eventually. They have military tech parity and hated each other but Gilgamesh is significantly bigger.
Asoka will remain independent. He was first to liberalism. He ran free religion and can trade techs with everyone. He cottage-spammed and ran free-speech. This gives him a tech lead. If Gilgamesh ever tries to attack Asoka, curaissers will smash against rifles, cavalry against infantry, tanks against mech infantry. Gilgamesh will not make progress.
Churchill will do his own cultural or space race thing. Annoyingly, Asoka convinced Churchill to switch and say in free speech. It will be quite late by the time I have nationalism myself and the spare gold to bribe him to switch. It will take time to accumulate the favourite civic modifier.
So the three players that will build the UN, in order of likelihood, are: Asoka, Churchill, Gilgamesh. I "just" have to convince the other two to vote for me late on.
What makes me believe that I can keep Gilgamesh happy? He built the apostolic palace and kept trying to win diplomatic. It's not possible for him to win, but, I keep voting for him and accumulate +2 modifiers.
For the next six centuries, the Khmer stagnates...
1280AD: Trade Astronomy to Alexander for engineering, literature, drama (for a moment he wasn't anyone's worst enemy)
1340AD: GIFTED printed press by Churchill
1350AD: researched nationalism
1420AD: researched gunpowder
1510AD: GIFTED education by Asoka
1515AD: researched chemistry
1565AD: researched scientific method
1640AD: researched biology
Upon slave labour, they built granaries, libraries, harbours, baray, theatres, colosseums, courthouses, barracks. After biology, grocers.
The world again at 1645AD
The diplomatic situation evolved as expected. Gilgamesh did not attack Asoka yet but will do so soon. They hated each other. Churchill was the only one I can safely trade with.
The United Nations built on 1730AD by Churchill. I needed votes from both Gilgamesh and Asoka.
I am confident Asoka will stand. Notice the diplomatic modifiers from the (defunct) apostolic palace accumulating.
Final civic switch. If my math is correct, even if the United Nations forces me away from hereditary rule, which later on it does, I have enough diplomatic modifiers.
1842AD: UN vote coming up. Just like the real UN, bribing for votes is standard practice. I could not do it with Churchill because 1 of the existing +6 points were from "fair and forthright". Bribing will only push it up to +9.
So there you go.
Irrelevant detail: I finally converted the barbarian city on 1836AD:
The barbarian city caused me trouble throughout the game. It was on a hill, with 40% cultural defense, guarded by 7 riflemen and a galley. They would harass me amphibiously with rifles every now and then. My muskets held the cities.
