Thanks for the quick replies!
I have been reading about ways to grow villages from Jeffry, crownvic, and Drewski. I saw you guys would supply villages demand if they had an industry. Also, you guys would send some food and pax/mail if there wasn't an industry there with a demand. Based on that cargo data file, I bet the demand in the villages would be zero for everything. I checked the demand for pax in those villages and its less than the 0 demand at a town station. I tried growing a village with my unused produce/uranium, and it worked. I think it would be better to make money on easy demanded cargos like food and pax/mail rather than investing them on the villages.
Did you guys find anything else out about the connection between revenue and city growth? Wondering if its like a revenue threshold for city that guarantees growth, its like a percent growth chance if city had any revenue that year, or its a percent growth chance that increases with higher revenue.
Also random question if I bulldoze an industry in a city marked for 3 industries by the map editor, I'll eventually get 3 again right?
