role-playing game system

A role-playing game system is a set of game mechanics used in a role-playing game (RPG). A game system is roughly analogous to a game engine in the video game industry.The system can take any of several forms.  Generic role-playing game systems, such as the d20 System and GURPS, are not tied to a specific storytelling genre or campaign setting and can be used as a framework to play many different types of RPG. Others, such as Dungeons & Dragons, are designed to depict a specific genre or style of play, and others, such as the first and second editions of RuneQuest, are not only genre-specific but come bundled with a specific campaign setting to which the game mechanics are inseparably tied. Some systems, such as the D6 System, are refinements of those used in earlier games.
