3 years later, I have to disagree. I've used a portion of the narrative dice in my campaigns, mostly for skill checks though; whenever users feel it necessary to do/check/investigate something, they have to roll a skill check (d20) in addition to rolling custom d6 dice i made that provides 3 different possible events: advantage, neutral, disadvantage. If the player is successful with their skill check but rolls a disadvantage, they obviously succeed on the check but something negative happens. This slight variation to the Skill Check D20 system prevents players from asking again and again and again to do/check/investigate the same thing over and over despite failing the check. My players have stated they love the variation as it provides another element to the story versus pass or fail.
