How easy would it be to have three different types of goods that city industries need?
I dislike the ‘all systems create goods’ model, as it is too easy. I would rather have oil -> plastics, Steel mill -> metals, Farms -> foods & ingredients.
I don’t really fancy lots of different industries (FIRS of OpenTTD was way too much for me), but having one oil well sufficient for all the goods in a city is just too unrealistic for me.
Is that easy to mod in the game? Not sure how it would impact demand and growth and whether it needs lots of changes..
