In "Collaborative Story," participants work together to gradually build an evolving narrative. Ideally, as each participant contributes a sentence, they are letting the next person carry the narrative forward.
You can adjust the rules to make the game last longer, simply by changing the contribution requirement from a "sentence" to a "word."
We have found "Collaborative Story" is best enjoyed by a more mature audience. Participants who are unwilling or immature have shown a tendency to disrupt the fun by arbitrarily "killing off" characters or derailing the storyline. Please be respectful of the ongoing narrative and other players when making your contributions.
