It looks like there are some simple, fairly mechanical conversions of how to interpret a particular die roll beyond the binary pass/fail (such as when to add a setback die to the opponent's roll, etc).  But then you get into Triumph and Despair rolls (and even to a lesser extent Advantage and Threat).  I'm curious how far to take the creative license the rolls seem to invite.

How have the GM's been interpretting the dice?  Do you allow the players to offer up suggestions?  Do you require multiple Despair/Triumph symbols for something really significant to happen?  Multiples of the "big" symbols should logically be a much bigger deal to the story, but as a way to compare the impacts of various symbols (singly or in multiples) what are some examples of how you've applied the results?

I love the idea of the dice allowing complex results, but there's a gulf between theory and practice that has me very uneasy.  What I want to avoid is seeming hopelessly arbitrary (and potentially inconsistent) with turning a roll into narrative.  I also don't want every result to turn into a debate.  Ideally I'd like the players to be able to contribute narrative here also.

So basically I'm bored as hell with pass/fail and scared as hell of this shiny new alternative.

As a GM, I'll won't just 'let' my players to offer up suggestions on how to resolve threat/advantage results, I'll *encourage* it.  If you've got 4 players, you've got 4 extra minds to figure out how, exactly, to make sense of, or describe what's going on in the game.  In my mind, the idea that only the GM gets to make that sort of decision is one of the *worst* aspects of many RPGs.

Take advantage of your players' own creativity.  If something they suggest is too much, or not enough for a given result, make suggestions on how to tweak it, or let them do something else with the 'leftovers'.

Once you and your group start doing it, the easier it gets.  This is what helped me as GM understand what can and can't do with various results, including prodding players to come up with thier own ideas for what happens.
