Prince Valiant: The Story-Telling Game is a licensed role-playing game published by Chaosium in 1989 that is based on Hal Foster's comic strip of the same name.
Description[]
In Prince Valiant, players take on the roles of knights in King Arthur's court, taking part in adventures styled after the Prince Valiant comics. The game is designed for children and young adults, with an emphasis on story-telling — designer Greg Stafford claimed that Prince Valiant was the first story-telling role-playing game. The basic game mechanics, covered in a single page, are intentionally simple so as to emphasize story-telling over rules. More advanced rules are available that include more skills such as Bargaining, Disguise, and Farming.
Although there is a gamemaster called a Storyteller, all the players are responsible for telling part of the story. As designer Greg Stafford explained in an interview: "Each player ... owns part of the scenario and must present it to the others, who themselves know other elements of the story, so everyone participates in the evolution of the plot."
