@ AquaVixen: I've built factories and filled storage with more of everything than I can ever use, explored (and built belts, power lines, and now railroad track) across most of the map, collected power slug that I almost never use, logged off entire biomes while living up to the Ficsit 'We do not waste' motto (my last play through counted individual items trashed on my fingers; the current play through stands at zero with tier 6 entirely unlocked.)
Sending products up the space elevator for credit (whether or not there is anything to trade that credit for) would give my factory purpose (why would Ficsit send pioneers to build factories if they didn't need what we make?) and provide a new, different challenge.
