Cities: Skylines - Industries Review (BodyBagger)
This is my favorite DLC, but only because it can be modded.
If you're using the Industries DLC, I highly suggest that you use the following mod: Transfer Manager CE v.2.4.25 by Sleepy (in the Workshop). This mod will allow you to direct vehicles from all industry buildings to other industry buildings in specific districts. This means you can force the game to use your own raw materials and goods from your own industrial areas (farm, forestry, ore, and oil) rather than the game forcing you to import everything. This is especially important once you start building factories that require raw materials and goods. It's a lot of micromanaging, but it's definitely worth it. If you rely on the game to do what it's supposed to do, you're going to be highly disappointed. Most of the problems that are mentioned in the negative reviews can be fixed with this mod.
Be sure to read everything on the Mod's homepage in the workshop. This will give you a better understanding of how the mod works and what to expect from it. Good luck!
