Since planets are resource generators now, I hope we can colonize all planets now (including those ubiquitous dead worlds from previous installments).
I wasn't a fan of asteroid mining in GC3. Same with constantly upgrading factories/research labs on planets and starbase modules. Its ok for a few planets, but going through a list of 50 or so gets rather tedious (esp. when all I want to do is force end turn). I'm curious to see how GC4 handles it. I do like the changes I've seen so far to the planet map, so I'm optimistic here.
I think it would be cool if you could "settle" a moon, asteroid belt, or other space objects with a constructor and build an outpost/starbase there so it will function like a resource-generating planet.
i only agree only on the part of ending I prefer to manually run my 48 planets.
