Shipyard in Getsu Fune: Asteroid Belt High Tech (Moneyprinter): Pharma Fab in Mars: Solar Plant in Mercury: As its kinda decentralized you will ned a few ships to keep it running (general guideline but fewer will probably work too):
Shipyard: 10 L TS
High Tech Fab: 10 L TS, 20 L Mineral, 10 L Gas
Pharma Fab: 5 L TS, 5 L Mineral M, 3L Gas
Solar: No Ships
Produces very little overflow of intermediat resources and lets you build massive Fleet (or become filthy rich).
I hope someone has as much fun with it as i did
