Been messing with outpost building quite a bit last few day, mainly to see what the game can do and whats available.
Whilst possible, I think it would be very difficult to get some kinf of factory going that produces all the high end resources.
Basically I think it will be down to the limitations set on how many A. Cargo links you can build in each outpost, but also B. How many outposts you can build in total.
The main factor is you can only build up to 3 cargo links in each outpost, each cargo link can only line to one another. So, you will need to "chain" these, as there is no way you will be able to get all the different types of resources needed to spider into one outpost, becuase at the most? each outpost is only going to be able to harvest 3? different types of resource.
You will then need to chain these, so if you start with two resource gathering outposts, these will need to feed into a "chaining" outpost, that has two incoming links (linked to the two resource gathering outposts) then one outgoing cargo link.
The outgoing cargo link could then feed into a similar "chaining" outpost that also could be supplied by a separate single incoming link, supplied by local resources, and then the forwarding link, and you chain them on like that. The idea is, if you build enough of these "chains" you'll end up with an outpost at the end of the chain that has every single resource available in the game, in which case you then build all your processors and could have that feed into large storage containers which you could then empty now and then to sell the goods.
The issue is you can only build a certain number of outposts in total, and I think you'll possibly find you run out of outposts before you can build enough like that in chains to gather every resource given how many there are. Maybe it is possible, I am not that far ahead yet but reckon it'll be tricky.
