Once I took over the most of the galaxy, I started terra-forming all the planets into Earthy type planets to maximize dust output. And I ran into a minor annoyance that asteroid fields cannot be terra-formed, and for obvious reasons. But then it struck me that it could be cool if you could reach the point of such technological prowess that forming a planet from asteroids would be possible. Just a thought.

would make sense to have it for a near endgame tech that allows for asteroids to become planets although i can understand gas giants being out of a terraforming list.



that feature should come with a drawback like a large asteroid field turning into a medium sized planet or a small asteroid belt turning into the smallest planet size.

That makes sense, or have a very limited population.
