User summary: StaMTaR, the Standard Method for Tasks Resolution in Role-Playing Games, presents a single mechanic for resolving any type of action or task by using an unmodified 3D6 compared to an action table the enumerates results by action difficulty. The difficulty is determined by the game master and the same task could have a variable difficulty for different characters depending upon their ability. Note, the product does not include a complete game of any genre; it is simply a core mechanic, as inferred by the title.
