This is the classic third person narrative game.
Get a suggestion from audience (e.g. Fictional title for a story.) One player is the writer and narrates the story. The other members of the team perform the actual scene that is being told including the dialogue. Players pass the advancing of the story back and forth between narrator and stage until the story has been told.
To explore the principle of narration and work as a team to advance a story.
One of the first hesitations a new team will have is to take over the scene from the stage. Most new players will just want the narrator to tell them what to do thus ridding themselves of any need to create a story. It is very important to get all of the players to advance the scene.
