During my first playthrough I eventually came to the conclusion that I’ll never progress much further if i keep building every small item one by one. I do not have much time to play the game, so blueprints came in handy. Since then I have never looked back.
You’re totally right though, there are many ways to play the game and they are all enjoyable. I bet there’s even players roleplaying a nomadic, explorative playstyle.
Hard to see with the screenshots what you mean with using the same belt for both input and output. Could you provide some simple sketch that shows the concept? It sounds very interesting and looks cool.
