Did a peacemonger game. 9 civs on a standard sized map, custom continents with 3 continents. Elizabeth, Gandhi, Hatshepshut, Lincoln, Pericles, Frederick, Mansa, and Zara Yacob. I was Orange. Turns out my continent was actually an island with only me on it. Fortunately one of the other continents was reachable by coast, so it wasn't really an isolated start. Delayed settling my cities in order to get the oracle, got metal casting, and build the great light house and the colossus. Settler spammed, and the 2 extras overseas traderoutes and 1 pop whipped libraries kept me in the tech lead, though just barely. My infrastructure was awful, way too many jungles, little production. My whipping arm got tired, and my cities were tiny. Everyone loved each other, and any trade I made, every other civ would get the tech the next turn. I mean, they must have literally been just gifting techs, there's no way they could have gotten any worthwhile trades every damn time.
So I get liberalism, and I'm forced to start working on my land, since the great lighthouse and the collosus are going bye bye soon.
Everyone is still happy with each other, nobody ever got below cautious the entire game, even with different religions. There wasn't a single war the entire game. People start switching to free religion. I pull ahead in tech in the industrial era. Decide to go for a diplo victory, since everybody loves me. Start signing defensive pacts in order to solidify the friendly rating. Build the cristo redentor, which is great for this. I switch to everybody's religion and favorite civic long enough to get to friendly, sign the defensive pact, and then switch civics and religion again to befriend the next guy. Unfortunately I get lazy and don't build the UN. Figured i'd get someone else to build it and just be the second candidate, but Gandhi pulls ahead in pop. After that I get sid's sushi, and plant down as many cities i can fit into my island, buidling a bunch more farms. It takes FOREVER for the next UN candidate vote to come up, it finally does, i win, immediately choose the diplo victory, and win by a landslide. Poor lincoln only has Mansa vote for him. I get Gandhi, hatshepshut, frederick, elizabeth, Zara. Pericles abstains.
