ok I am getting closer. morale is an issue. i will start some festivals to raise it. But I cannot grow HABs until I get the tech, which is some way away, and I need to focus some effort on my combat initiative.
I still think it would be better to leave this to the independants, but they never want any of my planets.
What I would recommend now is installing an Orbital platform to replace one of the Hab Units. The you could build a Palace, which would help provide Spice, Research, EP and Defense, improving this already productive world into one that will never be much of a problem. I once had a world like this during the Alpha, and it grew into a sector powerhouse in Mining, with enough Factory potential to pump out some Fighters if the sector defense fleet needed reinforcements.
Brutus Aurelius - agreed, in a well-managed empire, these types of worlds are really awesome. The right Planetary Construction tech can turn them from moderately profitable (as seen now) to powerhouses.
