A thought I'm having on the fail forward discussion; is this a division of responsibility question? Setting aside the tools they have to change "the fiction" and the gameplay concerns I have, it almost reads to me like the real debate is over who is responsible to propose a change in the game state.
FF says it's the GM; they should do something to break the status quo after a player action declaration fails. The other view seems to be that it should be the player, who either needs to deploy a different one of their limited tools or to abandon their goal and pick a new one.
Obviously there's an imbalance in the available tools players/GMs can deploy, but the question of responsibility seems to be the real thing at stake.
That’s one way to look at it I guess. Let’s look at Daggerheart again:
Keep the Story Moving Forward
“Every time a player makes an action roll, the story should move forward, success or failure. On a failure, the GM says how the world responds and keeps the story moving. This is often referred to as “failing forward.” A character might not get what they want if the roll goes poorly, but the story advances through escalation, new information, or some other change in circumstances.”
and couple that with:
Make Every Roll Important
“Action rolls in Daggerheart describe and resolve a moment within a story; these moments might be as short as a split-second dodge, as long as a full exchange of blows in combat, or an entire montage of chasing leads over the course of an evening.
Because the GM can choose to make a move in response to a player’s failed roll or a result with Fear, and since every roll generates Hope or Fear, only ask the players to roll during meaningful moments to ensure that every roll contributes to the story. Daggerheart is designed for cinematic play— when you provide information freely and allow characters to succeed at tasks in line with their skills, the moments where characters do roll carry more risk and weight. Failures should create heartbreaking complications or unexpected challenges, while successes should feel like soaring triumphs!”
