A role-playing game (RPG) is a game in which players assume 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 or character development. RPGs can be divided into several types, including:

• Tabletop RPGs: These are played with pen and paper, and often involve a game master who creates the world and story for the players to interact with.

• Live-action role-playing (LARP): These are similar to tabletop RPGs, but involve physical acting and movement rather than just verbal communication.

• Computer RPGs (CRPGs): These are video games that allow players to control a character or team of characters who undertake quests and may include player capabilities that advance using statistical mechanics.

• Massively multiplayer online role-playing games (MMORPGs): These are computer RPGs that allow thousands of players to interact with each other in a virtual world.

• Action role-playing games (ARPGs): These are RPGs that incorporate elements of action games, such as real-time combat and fast-paced gameplay.

• Japanese role-playing games (JRPGs): These are RPGs developed in Japan that often feature linear storylines, turn-based combat, and a focus on character development.

RPGs can include non-player characters, side quests, downloadable content, and larger story arcs. The genre often involves characters growing in power and abilities, and characters are typically designed by the player.
