I had today my first conquest of an alien homeworld. Admittedly, their tech level (nuclear pulse for engine) made the whole thing not too difficult, even if I learned a few things (don't station CVE brittle as glass nearby a planet housing PDC!).
It led to a few questions. The first, I have 2 colonies on the planet, one with their population and infrastructures, one with my units. Should I move the units out and then delete the empty human colony?
I did not fire a single missile against the planet or installations. The PDC were dispatched with gauss frigates, and then landing proceeded. Yet I'm a bit suspicious about the state of their infrastructures. Did the combat destroyed part of their installations? Was it the firing of gauss turrets against the PDCs that did collateral damages, or the ground fighting?
