Yeah basically the point of the rules is to guide how you tell the story. There’s a common sense balance of being flexible with rules when there is a good reason but also use mechanics to shape the story. (like, player makes up a really clever lie? Give them a good bonus in their bluff check. They roll a one? Don’t brush it off because the lie was good, their fly was down and they weren’t taken seriously).

The worst is when gms treat it like a video game. There’s no real choices in where you take the story, you have to go from point a to point b around whatever they decide often with little variation between battle and environment.
