Role-playing video games (commonly referred to as role-playing games or RPGs, as well as computer RPGs or CRPGs) are a video game genre where the player controls the actions of a protagonist (or several adventuring party members) immersed in a fictional world. Many role-playing video games have origins in pen-and-paper role-playing games(such as 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. A common criteria for whether a game is an "RPG" is whether the game has a complex storyline, and whether the character goes through different places, fighting bosses and communicating with both friends and enemies.
