I should clarify that I think “good/bad PbtA” is entirely a construct of the PbtA fandom community. There are factions of players who feel like they’ve got a clear bead on what the framework does well, so they measure PbtA games based on that rather than on whether the game does what it says on the tin.

And that’s why you can have bad hacks that are good games. I’m not sure you can have the inverse, though!
