Not a very good game, I had no idea how things worked. Science was way ahead of seats and I had to vassilize more civs AFTER building the UN in 1460AD.
The Apostolic Palace was a waste of good hammers since our religion never reached Native America and Spain ran no non-state after completing the Shwedagon Paya. Our relations with everyone suffered hard as turn after turn we had to refuse to join wars at the time that our army was still futile.
In the late game, the Inca and Aztec capitals flipped back without warning, but that made little difference.
The challenger handicap was quite fundamental. Losing the food resources meant not just no silver, but also no early access to gold. We found a decent spot for the capital 3 tiles east.
