As you ll understand this is a newbie's question 
So, what's with the galactic resources? Especialy the ones that are in the middle of nowhere. Are they worth mining? Do they add up to my civ? Do i simply keep sending constructors to upgrade them or i must also sent ships like freighters to...erm, "carry" the stuff back. Especialy with the economic resources. In the mission i m in i have 2, and i don't really see any finacial boost from them. Of course it might be just me.
Note that i m talking about galactic resources and not starbases with modules. And also about the ones that are far far away from my planets. I simply mine them and that's it? Do i need more starbases to stack them all the way back to my planet.
Thank You
