Roleplaying, or role-playing, is a term describing the act of playing a self-invented role (character), often done through games, with game masters. Do not confuse roleplayers with actors, since roleplaying gives the person an unlimited choice what to do, while acting always centers around a script or story. However, there are an infinite amount of different kinds of roleplays, with varying rules, goals and ways to play.
