ABSTRACT
In Chapter nine we suggested that the Experience Manager needs a metadataencoded script that represents the story so that it will know when the simulation is deviating from the path that is planned. Without such a script, the system will allow the participants to have an experience that does not provide all the dramatic moments intended by the writer. In addition, in a simulation based on delivery of media elements, not having such a script would also mean that the participants could very well take actions that called for media elements that do not exist, and so the participants would find themselves facing a blank screen abandoned at the edge of the virtual world.
