Statistics for Rolplaying

From publisher:

What does it mean when a game developer says a task is “easy”? What is “dangerous”? Players have an intuitive sense drawn from world experience. When gameplay does not align with that intuitive sense, players complain.

Statistics for Roleplaying takes the probability mechanisms of several popular game systems and places them into the context of real-world amortization tables. Doing this provides a sense of the “feel” of a mechanic. Players and game masters, hopefully, will find this a tool in choosing when to roll and when not to roll, as well as choosing difficulties that better target the intended feel of your game.
