Very elegant, very simple.
It feels like a great additional tool to add to the Player Skill side of the Player Skill/Character Skill distinction. It allows for the game to take a step away from the numbers on the character sheet for a moment and enter a different kind of game-space where the outcome rests on a whole different set of conditions.
It gets me thinking about other ways to incorporate these kinds of “real-world contests” into a game.
Is any one else incorporating things like this?
Is any one doing so with real-world contests that are not so…oppositional? E.g., have all the players play a game of “telephone” to determine the outcome of a situation–if the sentence successfully makes its way around all the players, then they party succeeds.
