I was thinking adjusting the player’s roll (like some DMs may do with hidden DCs in D&D). Since everything is open and player-facing, that would be harder to do. The ways I’ve seen thing go wrong were arguably mistakes rather than intentional (e.g., having the consequence on a 4–5 result in Scum and Villainy negate the success).First, the gamemaster never rolls in PbtA or FitD, to my recollection, nor do they control any numerical unknowns, so fudging in the D&D sense is impossible.
This seems like an expansive definition of “fudge”, though I expect digging into the details would be getting a bit off topic for this thread.Second, literally everything about proper gamemaster adjudication of these games would be considered fudging in the context of D&D.
That was also my impression, but I thought it was worth clarifying.Regarding the remainder of your post, I don't get the impression that you and I are in disagreement on most of what is being said in this thread.
