I agree with this. Diplomatic victory is a problem, if you have enough gold you can buy city states when its time to vote, however I´m amazed that AI Civs who have thousands of gold are not using it to do that.![]()
A recent thread described a diplomatic victory in which the player won against immortal AI, each tens of thousands of gold.
