From publisher blurb:
Tall Tales is a narrative roleplaying game for three or more players. This zero-preparation game features enough structure to move the action along with plenty of room for creative and cooperative storytellers to spin rich and engaging yarns.
Tall Tales is based on the Protocol game series. Players take on the roles of directors outside the action and characters inside the action, using the ebb and flow of four different scene-framing styles to tell meaningful stories about characters in crisis: Vignettes, Interrogations, Interludes, and Ensembles. Each story explores unique player characters dealing with the adversity of the particular situation and their own personal issues in the best dramatic fashion.
Tall Tales requires a deck of cards (with Jokers) as well as tokens to track Drama Points and Grit. It presumes some understanding of GMless game protocol: scene-framing, shared authority, and so on.
