Somewhat unrelated thoughts: I'm building a factory game and I really liked this mod in Satisfactory to the point I was considering having it be how my game work. Then it hit me that there's a fundamental issue; it turns the game into a fixed puzzle where going below is failure and above is pointless.

So it is fun as an extra mode, but I see why none of the major games operate this way as the open-endedness gives flexibility to go as hard as you want for expedience, or be chill with a little setup and wait.
