In Rebellion, the resource management was very simple, each planet had a different amount of raw material sources. You would set up a mine and a processing station. You had to mine and process material to build anything. In order to be able to build something you had to have manufacturing points. For every pair of mines and procing plants on each planet you had you got 50 points. Everything cost manufacturing points to build plus time.
I imagine something in a more realistic manner going to happen here.
Go big or go home.
