I also think it would be nice if industries shipped to commercial places. Perhaps change generic “goods” to something that industry ships to commercial areas, have a number of processed materials and “industry” will only produce “goods” when they receive 3 or more types of processed materials. Although I think a reworked economic system is something you could get away with putting in a paid DLC, because frankly the base game is adequate as it is in this regard, I wouldn’t expect them to put a bunch of time and effort into creating a whole load of new content for free. it could also maybe include a tweaking of city growth to promote more specialisation. If there’s lots of industry, maybe that would lower residential desirability (makes sense because of pollution). A strong commercial sector could encourage residential growth and availability of “goods” could encourage commercial growth (with industrial growth being promoted by the availability of manufactured goods and transport links). Just some thoughts.
