Editing Story structure (section)

=== Interactive narrative ===
An interactive narrative is one which is composed with a branching structure where a single starting point may lead to multiple developments and outcomes. The principle of all such games is that, at each step of the narrative, the user makes choices that advance the story, leading to a new series of choices. Authoring non-linear narrative or dialogue thus implies imagining an indefinite number of parallel stories.

In a [[gamebook]], readers are told to turn to a certain page according to the choice they wish to make to continue the story. Typically, the choice will be an action rather than dialogue. For example, the hero hears a noise in another room and must decide to open the door and investigate, run away, or call for help. This kind of interactive experience of a story is possible with video games and books (where the reader is free to turn the pages) but less adapted to other forms of entertainment. Improvisational theatre is similarly open-ended, but of course cannot be said to be authored.
