I'll preface this by saying I actually really liked the basebuilding mechanics in Fallout 4, and always built my settlements up to the standards and connected them in a sensible way. It felt like bringing a bit of life and something of your own to the world!
So, I've been thinking about how to go about settling interesting planets we might come across. Will you build on planets with settlements already on them (if that's possible?), or will you search for your "own" planet and claim parts of it as yours? Will you disperse you settlements across many systems, or rather focus them in a single system?
Personally, I'll probably go for the latter option of centralization. Maybe I'll start with the Wanted trait and found my own empire in a single system, building that system up to the max before spreading out :).
This is also my first post in the Fediverse, and I'd love to hear your ideas!
I think one of the biggest determining factors for me will be the tone/vibe of the planet.
For example: music, aesthetic, local fauna, and things like that. If all those factors combine into a friendly/inviting/upbeat atmosphere then I'm a lot more likely to want to colonize it and spend a lot of time there.
But, I guess it's possible that most of the planets could feel pretty similar. In that case, I want to colonize a frosty planet, a swampy planet, a SUPER HOT planet, etc.
