A role-playing video game (commonly referred to as role-playing game or RPG, and in the past was also known as computer role-playing game or CRPG) is a video game genre where the player controls the actions of a character (and/or several party members) immersed in some well-defined world. Many role-playing video games have origins in pen-and-paper role-playing games (Including Dungeons & Dragons) and use much of the same terminology, settings and game mechanics. Other major similarities with pen-and-paper games include developed story-telling and narrative elements, player character development, complexity, as well as replayability and immersion. The electronic medium removes the necessity for a gamemaster and increases combat resolution speed. RPGs have evolved from simple text-based console-window games into visually rich 3D experiences. Since the 1980s, Role-playing is the most commercially viable video game genre in Japan, and has more market share of any other genre in the japanese gaming industry, although in the 2010s first-person shooters and western iOS and Android games were becoming rapidly and increasingly popular in that country.
Role-playing video games use much of the same terminology, settings and game mechanics as early pen-and-paper role-playing games such as Dungeons & Dragons. Players control a central game character, or multiple game characters, usually called a party, and attain victory by completing a series of quests or reaching the conclusion of a central storyline. Players explore a game world, while solving puzzles and engaging in tactical combat. A key feature of the genre is that characters grow in power and abilities, and characters are typically designed by the player. RPGs rarely challenge a player's physical coordination or reaction time, with the exception of action role-playing games.
