I think it is important to remember that while "play to find out" is the state playstyle intended for Daggerheart, and advice is given to the GM to "hold on lightly" and all that, there aren't actually any mechanics in Daggerheart that enforce this. You could play DH as linearly as any 5E game, as far as the mechanics are concerned, and use Hope and Fear for results for the metacurrency alone and it would work fine. Now, I would not run it that way, but I also don't like running 5E or any RPG that way. But, again, DH does not actually enforce its stated preferred play style with mechanics.
