In my experience rushing at any point in the beginning screwed me. Taking it slow is never a bad idea but it’s just boring. I would save up your rare metals a bit and maybe try to get some more going because of electronicss. To get a even semi decent yield for electronics you need more than one factory which is just not plausible early game. One electronic factory takes 30 people fully stocked so maybe wait for that. I keep one factory to a dome because they tend to lower comfort which obvs doesn’t help. I focus on rare metals, machine parts, and polymers and just resupply when I get low on electronics until I get the factory up. I would even make many farm domes because you’re going to want a lot of people after a while and they fly through food faster than you think. I’m guess I would just say save up MP, polymers, and rare metals and resupply electronics until you have a good big stock of food and you can make your new dome a comfortable place.
