In my last game, I got unique opportunity to go for diplomatic victory. It was a game with single runaway AI that had whole continent for himself (after destroying other 2 civs there). At one point he invaded my continent, where he destroyed second best AI. After that, he got in war with me, which ended after I took all his territories on my continent. Another weird AI behavior here was that all his cities on my continent were puppets, which prevented him from purchasing any reinforcements (but this isn't point of the thread). This also lead to me liberating 3 city state and one civ, which gave me 4 guaranteed UN votes. Due to that, I aimed for diplomatic victory (and started working a bit for space ship victory as backup). With 2 of my votes from UN, 4 guaranteed and 4 additional from other allied city states, it was enough votes for me to win the game. I needed a lot of gold for this, to keep 4 city states happy until voting, which was tough for me (spent around 3.000gp total), considering that influence was dropping -2 per turn. Now, what bothers me, is that AI never tried to sabotage my diplomatic efforts. He earned around 300-400gp per turn, and had gold reserve almost 10.000gp big. So why he didn't buy out my CS allies, one turn before vote? It just doesn't make sense, and made my victory too easy. Thoughts?
