In my first proper campaign, I have found one hell of a world. MEGATONS of minerals at high accessibility. Only now, with >10 populated colonies spread among as many systems, do I realize that alpha centauri is a special system. Adjacent to sol, and a dead end warp-- nothing can come from the back except invaders when I turn them on and nothing comes out but minerals and product. One step up from earth theres a world with 84 million neutronium and 2 million corundium, both in shortage here, at abundance 1, but only modest other mineral content.
How typically do you find worlds like this? I mean, I don't imagine I'm ever really going to have shortages of much of anything. And now that I have 2000 mines on Penumbra, and another 2000 in another (less) major system, I'm really mining with a vengence here. To find something like this so close and so rich seems... unlikely.
