This is the place you will frequently go to if you have a question on how the game functions, what mechanics work in a mod, or when you should do something to avoid eminent disaster in your city.
Ever since the oil fields of modding for SimCity (2013) burst open, there has been no place of formal documentation for any of those mods. How are people supposed to know the specifics of what one does or how it works? Could someone greatly improve their experience with mods if they knew the unusual quirks and best ways to accomplish a style of a city?
