RPG dice systems have a particular bonus in the way they invoke player emotion, as those dice systems determine success or failure of the player’s actual alter ego, his character. In the best of those designs, dice not only provide randomized conflict resolution, they also provide a foundation for the emotional experience; tangibly manifesting the world to the players as they manipulate the world’s totems—the dice.
Quotes about dice
Part random number generator, part talisman, these objects [the dice] viscerally connect the player with the game systems, precisely because the player manipulates the outcomes of these systems by rolling the dice. Talk all you want about digital media being ‘interactive,’ I posit that there is no greater degree of interactivity than the kind a player gets when they have the dice in their hand and are trying to manifest a particular result to appear, face-up, on any particular throw of the dice.
