Trust me when I say you don't need any thinking for Factorio, if you want to do it like that. It's very forgiving, except maybe the trains, that one you need to think about to figure out how it works. You can do the bare minimum and you can optimize the crap out of it and if you want to optimize it without thinking you can just look up the plentiful guides online.
Saying all of that, for me Factorio suffers from what all strategy/builder games suffer from, a boring endgame. I'm hoping Space Age doesn't just move the boring part to later.
