I’m a lazy bugger, so just want to save this somewhere for my own easy access. Originally from Letrange’s research on whether a single character can get all planetary resources.
Temperate: Autotrophs, Complex Organisms, Micro Organisms.
Lava: Felsic Magma, Non-CS Crystals, Suspended Plasma.
Gas: Reactive Gases, Ionic Solutions, Noble Gasses.
Ice: Planctic Colonies, Aqueous Liquids, Heavy Metals.
Barren: Noble Metals, Base Metals, Carbon Compounds.
So with 5 planets you can get all types of resources.
