Wow! Want a game that is free and will REALLY scare you? (PC
   only) How about a game of *awkward* - Facade

   It's 167 Megs so have Time and Space at hand.

   You're an old friend visiting a married couple on the verge of a
   breakup. You have to try to not get kicked out of their fancy
   manhattan apartment. The whole sensation is awkward - and we've
   *all* been in situations like that. Maybe not as scary as the
   latest *Slender* video game #slenderman but a way different kind
   of scary.

   Description: ''This is an artificial intelligence-based
   experiment in electronic narrative

   Facade is an artificial intelligence-based art/research
   experiment in electronic narrative an attempt to move beyond
   traditional branching or hyper-linked narrative to create a
   fully-realized, one-act interactive drama.

   Integrating an interdisciplinary set of artistic practices and
   artificial intelligence technologies, we have completed a five
   year collaboration to engineer a novel architecture for
   supporting emotional, interactive character behavior and
   drama-managed plot.

   Within this architecture we have built a dramatically
   interesting, real-time 3D virtual world inhabited by
   computer-controlled characters, in which the player experiences
   a story from a first-person perspective. Facade was publicly
   released as a freeware download / cd-rom in July 2005.

   You, the player, using your own name and gender, play the
   character of a longtime friend of Grace and Trip, an attractive
   and materially successful couple in their early thirties.

   During an evening get-together at their apartment that quickly
   turns ugly, you become entangled in the high-conflict
   dissolution of Grace and Trip's marriage. No one is safe as the
   accusations fly, sides are taken and irreversible decisions are
   forced to be made.

   By the end of this intense one-act play you will have changed
   the course of Grace and Trip's lives motivating you to re-play
   the drama to find out how your interaction could make things
   turn out differently the next time.

   This work is unlike hypertext narrative or interactive fiction
   to date in that the computer characters actively perform the
   story without waiting for you to click on a link or enter a
   command.

   Interaction is seamless as you converse in natural language and
   move and gesture freely within the first-person 3D world of
   Grace and Trip's apartment. AI controls Grace and Trip's
   personality and behavior, including emotive facial expressions,
   spoken voice and full-body animation. Furthermore, the AI
   intelligently chooses the next story ''beat'' based on your
   moment-by-moment interaction, what story beats have happened so
   far, and the need to satisfy an overall dramatic arc.

   An innovative text parser allows the system to avoid the ''I
   don't understand'' response all too common in text-adventure
   interactive fiction.

   The process of building Facade has involved three major research
   efforts: designing ways to deconstruct a dramatic narrative into
   a hierarchy of story and behavior pieces; engineering an AI
   system to reconstruct a real-time dramatic performance from
   those pieces that integrates the player's moment-by-moment
   interactions; and understanding how to write an engaging,
   compelling story within this new organizational framework.

   Along the way we have learned hard lessons about what works and
   what doesn't in the design and engineering of interactive
   stories, and developed a deeper understanding of what it will
   require to create even more generative story systems in the
   future.

   There are great hopes this project will attract enough attention
   to facilitate the birth of a new game genre.''
