My factory is currently in full flow, and we are manufacturing every possible part that we can on site. We are essentially just importing the bare minimum and everything is created in house to reduce costs.
Due to me being a bit of a hoarder, we have far too much stock of parts, so an idea would be to sell these parts to a competitor as a stand alone part - much as we import them early on in the game.
It would push the factory owner to research parts and manufacturing, and to have stockpiles of parts worth cash rather than just sitting in stock. It could even be a researchable upgrade for the current export slot.
Sorry if there is already a post for this, did a search but couldn’t find anything.
