Last Saturday was my first experience of a Storygame, Quest, at the London Indie RPG Meetup Group - London Indie RPG Meetup Group (London, England) - Meetup - we cooperated to create a story of galactic derring-do, missing space princesses, AI spaceships, space knights, mutants, interstellar war, and the Ultimate Secret.
It was a lot of fun, and there was some playing of various roles (eg at times I played the heroic space knight Gordon and the villainous General Veers, both serving King Arthur of Space-Camelot), but I'm uncertain that it could be considered a "Role-Playing Game" as I understand the term. I wonder what other people think - are Storygames RPGs? Are they a different sort of game?
