So in short:
Extraction+ Refinery+ Industrial= Machinery used for High Tech & Agricultural
Extraction+ Refinery+ High Tech= Tech, Electronics & Medicine for most economies
Extraction+ Refinery+ High Tech AND Industrial+ Agricultural= Food type supplies
Types of out posts and settlements not listed merely offset losses of things like security and population drops form other types of bases while anything orbital I believe is able to offer those materials based on it's type while larger orbitals are merely a colony that handles all trade in your system in one location. Granted this is supposition based on what we CAN build and knowing this is enough for me to be ok building out my systems now. I also believe without evidence that the type of planet you place an extraction site on determines the quality of the materials it mines.( I.E. A high metal world will get you titanium from the refinery while an ice world may get you copper from the refinery or something like that). You probably should do your best to align your outpost type with the settlement types as well but my theory is if you put down extraction and refineries to cap your output first then expand into High Tech and Industrial then Agricultural after you will set yourself up to generate a ton of commodities and have a self sustaining system. IF it works as intended.
Okay. That’s been probably dragging me down. I noticed a surface industrial port was really doing nothing as far as offering products to sell but I have focused on getting the system to show up as Industrial. So sounds like I need to now place some mining settlements. I think they work as both extraction and refining right? I was wondering if that was not the case.
Question develops then, does a nearby extraction system do the same thing by creating trade routes?
