Well gold is a mineral...

Personally I enjoy the absence of a monetary system, at least for some empires, because money is really a social population manipulation system, which not all empires would require.

It would be interesting if some empires needed to worry about internal political and monetary problems, and others didn't.

I would like to see population consuming resources (should be different types and amounts for different species - not everyone eats orgs).

I could also see places for labor, trained labor, and robot labor as resources. Certain empires could also be required to feed and not "jettison" nonproductive population, as well.
