Motivation Comp. Models New Content & Content of Narrative Experiences PCG & Procedural Narrative Content Generation Systems Joe Bear was hungry. He asked Irving Bird where some honey was. Irving refused to tell him so Joe offered to bring him a worm if he’d tell him where some honey was. Irving agreed. But Joe didn’t know where any worms were, so he asked Irving, who refused to say.

Authorial Bottleneck Problem • Input required by OPIATE Characters, Locations, Narrative Function Attitudes, … Props, … Sequences Once upon a time, Bonji ran into Lili, Mimo and Bibi, three friends who lived in a hut. In a field nearby lived Snomm who had a Magic Mirror. Past the field and further into the woods lived Blobar. In the other side of the woods there was a little town where Sergeant Lip and Corporal Foot lived. They stole the Magic Mirror. [...] Opiate [Fairclough 2007] 17
