Look into the AI citys, mostly all AI civs now at -50 to -200 gold a turn. As thunderbrd said, AI needs to be reprogrammed/rewriten. AI is totaly bugged now and unable to improve propertys and unable to manage gold, look education and crime values on your game in the AI citys. Changing these options will not fix that. India, australia, zulu, aborigines, sitting bull... france... all to -50 to -200 gold a turn now, the others will follow when they have the tech that gives them the crime, they build more citys and useless stacks of troops, log rams.
Also yourself you got -130 gold now, even if you go 100% gold you will do -120 gold currently, you did autoplay right? So you will go bankrupt in some turns also...
Also AI never builds community disscussions, what makes them to not be able to build myths fast at start, takes them to lang to get knowledge inhertiance, making the AI fall back in research alot because they can start to build myths buildings to late.
So dont tell me that i think -50 to -200 gold per turn on some AI civs is wet and good.
Some AI civs get -800 education and +600 crime on your save, at about 380 turns in your game if i remember correctly. Agressive AI is not enabled in scenario. Tech diffusion is unrealistic, will not fix the AI bugs and cheat the AI to keep up with the player or the player with the AI, what we need is to make the AI able to build myths fast, so same chances for all. That meens AI has to the free community disscusion building from start or they should be able to build it. Raging babarians is no problem here not many babarians on map now and the AI has enouth defense, its just the bugged AI that cause these problems.
So turn further your savegame 100 to 200 turns and provide save again if you like, i will look into this then again and see how mutch gold is left on the AI civs.
