Prom Week is the creation of a group at UC Santa Cruz that includes Michael Matteas, one of the people involved with the creation of Facade. Like Facade, Prom Week is an attempt to create interactive drama, a sort of theatrical story with multiple characters and some agency by the player to shape the path and outcome of the story.
True interactive storytelling is, of course, an enormously difficult technical problem that many have attempted to solve without great success, despite the efforts of some of our most creative designers. Facade succeeded, in a limited way, its success and also its limitation dependent on the fact that it did not try to solve the general problem, and instead create a single, hard-coded, and specific work.
Prom Week is an ambitious attempt to solve the problem more generally. In a fashion reminiscent of Crawford's Trust & Betrayal, it tracks the social graph among a handful of characters, particularly how much they like or dislike each other. The underlying engine also tracks specific traits of the characters, and how they respond to traits of others, and provides a dialog system, not unlike the story-telling system of Tales of the Arabian Nights, that interpolates specific terms into generalized but prescripted dialog in response to certain conditions.
