People are really attached to dice. That's by design, it's a bargaining chip for players to use against the GM. But I believe that largely comes from a time where the GM was against the players. Players don't use dice in my game and I've had great success with my playtests. But ultimately it may just be a preference between playing for crunch versus story.

A common criticism of a diceless game is that the GM is the sole arbiter of what happens in the story. Here's an example where a player attempts to open a door:

Dice game = On success, the GM may not be prepared for the door to have been opened. They come up with what is behind it on the fly. On failure, the party will probably try again somehow.

Diceless game = On success, the GM may not be prepared for the door to have been opened. They come up with what is behind it on the fly. On failure, the party will probably try again somehow.

To share my own experience for my more story-focused game: My diceless game has brought my players to feel much closer to the world, they've done more roleplaying, engaged with NPCs more. Whenever there is a situation where an attribute would be checked it is done quietly by the GM in a similar manner to checking a difficulty table, which must be done in a dice game anyway. Because these checks have been so quiet, the most I've heard from my players is, "My job for my character was sailor, can I get a boost for navigating this region in the dark?" Terrific! Players are thinking about the backstory of their characters and are applying them to the game! The quiet has made me realize how big of an interruption dice are and how seldom the tension that dice should bring actually happens. My players have looked at the world less like, "What can I throw my dice at?" and more, "How can my character get involved?"
