Intermediate items are all that the remain of an ancient alien civilization, escaping from the planet long ago. They are buried and scattered across the map. With fluids, too.
I can add selected things from other mods, and try to generalize it a bit (I do this in Deep Pockets to guess what is an "intermediate item" as the direct example).
The most wanted ones are what? AAI Industries, Krastorio2, Space Exploration?
