Has anyone any idea of how to tweak the game to prevent the AI building cities over the whole map...? I'm getting really annoyed, first of all, of the AI sending repeated settlers into my territory to reach a patch of land that is completely worthless and arid, but unoccupied, and second of all, it sucks to have the Sahara filled with cities (of lots of different countries even).
I don't know if it would help to lower the food output of desert and tundra tiles. Since cities terraform their base anyway, they AI might end up building a city there anyway, surviving because of the city tile, but not starving to death, which would at least help for something.
There's a reason that the Earth's surface isn't inhabited all over...
