My Life with Master is a game about role-playing the servants or minions of an evil Master or Mistress.
The prototypical setting of the role-playing game is in an unspecified Central European country in the early 19th century. Players in the game portray the Igor-like minions of an evil Master (or Mistress) who preys on the nearby Townsfolk.
Like most role-playing games, there is a Gamemaster (GM). In this case the GM plays the part of the Master. However, the GM and players together are supposed to "design" the Master, in terms of defining his "Wants", "Needs", "Aspect", and "Type". These traits have no explicit game effect, but are used to define the desires and mannerisms of the Master and how he interacts with the Townsfolk and his minions. Masters have two game statistics, "Fear" (a measure of his power over minions) and "Reason" (how much minions and Townsfolk can resist the Master's control over them).
