Sorry to resurrect this thread, but my question is related - just built my first terraformer ship, and I'm wondering what planets I can use it on. I get that it can't be used on a gas planet, does that mean it can be used any place else? I've moved it over to a few un-occupied planets (rock, lava, ice, etc) and once it's there, there's no button to press to make it do anything other than move/fleet/scrap. I see in Tsagoth's earlier post the planet has to be mine before I can terraform it. What ways do I have available to do that? Will an outpost do? Can I even plant a colony there to make it mine when its current terraform level is only 20% (or even 0% for example)? Thanks for the help!
