Is there any way to clear out a planet you own so that you can terraform it? Or do you have to grant it independence and then bomb it?
You can also terraform it into something unpleasant.
You can exterminate the last pop and unsettle the planet by doing so, yes. But be aware that your borders won't be projected from that place anymore. If it's a border world then put down a frontier outpost before purging to be on the safe side.Yeah, I am not experienced enough playing evil overlord that I know whether you can 'unsettle' the planet by exterminating the last pop. But I am not there in my game yet, so I will wait and see if I can purge them all once i annex the planet.
Who doesn't love a good act of genocide with your cornflakes?
