I won a science victory. I can't believe it. The AI is stupid because Pacal should have won Science victory decades ago. They had 20k gold and were 9 techs ahead of me at one point. They started the Apollo program many turns before I had even researched it. I had gone so far in the game that I just wanted to see how it ended. I never gave myself a shot until I started popping out a few great scientists near the end with faith and GPP and noticing Pacal slowing down with his spaceship parts.
I loved the first half of the game though. Normally when I play I don't really think about diplomacy with the AI. I was careful this time. I made sure not to piss anyone off. I denounced others when there was a clear majority of denouncements. I really took care of diplomacy and I think that's what won me this game. I was able to make other Civs declare war on each other to control everyones soldier count and hopefully take their minds off a science win for me to come from behind and take victory. The AI is still dumb though.
Brazil and Pacal were fighting for a culture win but their base culture was too much to outdo each other.
Egypt and I had beef in the first half of the game. They continually backstabbed me. They took one of my cities early and I was able to defend about 3-4 additional attacks. The next time they declared war on me - and I provoked it by stealing some land with a great general - I was going to wipe them out. I had the army and I'd defended so often it weakened their military. So I went in and took about 5/8 of their cities. Liberated a CS and probably took one more city than I should have as the last one got me a 'major' warmongering label but it didn't seem to affect anyone diplomacy wise (how come?). All the other cities were 'minor'. Was it because I liberated the CS? Or because Egypt declared war on ME and not vice verca? Or because they KEPT on declaring war on me?
I offered peace after that and turtled for a long time. I recuperated and built up all the cities I'd just taken over. I still hadn't found half the city states or explored the other continent yet. The world congress was established and I met everyone. I should have taken note of the scores and it wasn't until I started exploring the other island did I realise that Pacal had a huge lead and was 9 techs ahead and thought... I can't win this. My Mac was struggling in the last 200 or so turns so I wasn't up for a war. I used diplomacy to try and get people to war with Pacal but I didn't have enough loot to do so. Even though everyone had denounced him and I was friendly with everyone. Brazil was an issue for a while but I managed to get Poland to go on multiple battles for me to protect me from a Brazil attack.
So I turtled. Minor micromanagement. Not tile to tile but shifting between production/wealth/science striving and hoping for a science victory. I thought for sure I would get done by Pacal in the last turn. We both had one last spaceship part left to build. But I got there first! Relief!
Really enjoyed the game overall. Big learning experience and I now have patience to play a really long game. I usually don't enjoy war but the last few games I've played I've really embraced it. The continuous defending of Egypt and eventual takeover was a lot of fun.
Oh I did the pillage 9 farms achievement during my counter-attack on Egypt
Very happy with that. Unfortunately everyone bar Brazil (who eventually turned) went Order so I had to follow suit to do with my diplomacy plan and to stay happy. I also didn't capture an overseas city.
I'd like to attach the save to get your thoughts but it exceeds 2mb unfortunately. Any ideas?
EDIT: Also I was never going to finish ANY Ideology tree. My culture too was extremely poor. I had full Liberty, Honor, Rationalism and Wagon Trains from Commerce. Only unlocked 3 Ideology tenets. (4 if you count the one I lost when I changed Ideologies).
