Here's an update.
Possible name for SJmod: Gritty Economics
The stuff you've already seen, plus refined weapons, and a very new economics model.
Minerals are still here, but organics and rads are out.
Replacing them are workers and energy.
Build any of a wide variety of power plants to charge up your energy stores, and build up the training and support facilities for your spaceworkers.
Facilities also have maintenance, so you have to keep things balanced.
If you build way too many mineral miners without the infrastructure to back it up, you'll find your empire experiencing blackouts and worker shortages.
