Do you like games at all? Almost any game would be “more efficient” if you could just write code to declare yourself the victor. Games - for that matter, pretty much any leisure pursuit whatsoever - are not about efficiency.
For example Doom Eternal is basically, IMO, one of the best games ever made, because it's one of the only games where the combat loop gets a physiological response from me. I can't play it at all if I'm in the wrong headspace, but it's amazing when I'm in the right one.
Factorio really has to hit the same sort of "zing!" feel. Programming-wise for me, it's the feeling of unbridled power at just tearing things apart to refactor. Because that's a hell of a different feel to the day job.
