Role playing game in the context of "Setting (narrative)"

A role-playing game (sometimes spelled roleplaying game, or abbreviated as RPG) is a game in which players assume and play out the roles of characters in a fictional setting. Players take responsibility for acting out these roles within a narrative, either through literal acting or through a process of structured decision-making regarding character development. Actions taken within many games succeed or fail according to a formal system of rules and guidelines.

There are several forms of role-playing games. The original form, sometimes called the tabletop role-playing game (TRPG or TTRPG), is conducted through discussion, whereas in live action role-playing (LARP), players physically perform their characters' actions. Both forms can have features of a storytelling game. In both TTRPGs and LARPs, often an arranger called a game master (GM) decides on the game system and setting to be used, while acting as a facilitator or referee. Each of the other players then takes on the role of a single character in the experience.
