Like, not technically how, but emotionally? If I spend too much time messing around on a platform, critters inevitably attack my base. Even if I build a fortress, I worry that something will run out and guns will run out of ammo... or that something will run out and The Factory will grind to a halt. I could just stack up a vast area of capacitors and rely on lasers and a fission reactor, but is this really what you guys are doing?
How do you emotionally detach from Nauvis and commit to not being able to troubleshoot on the home factory? Heck, once I establish factories on other planets, how do I leave them to return to Nauvis and not worry that they'll be overrun??
When Space Age was released I restarted, solo, with a new base, and I'm getting close to building a traveling platform; how do I ensure the security of Nauvis before I depart?
(My first, and as yet only, station attached for giggles)
With some bots back on Nauvis, you can absolutely troubleshoot and even/improve fix stuff from other planets.
Of course, fortifications are important, and you should make sure you've got your factory fairly protected first
Without spoiling anything, all of the planets have different challenges that require different solutions to make stable. Definitely part of the fun is that you can't copy/paste solutions between the planets
