Façade (2005 Video Game) (en.wikipedia.org) AI

Façade is a 2005 interactive drama in which the player converses via text with an AI-driven married couple, Trip and Grace, in an open-ended story about their deteriorating relationship. Built using natural-language processing and an AI “behavior language,” the game was praised at launch for its conversational design and storytelling ambitions, and later developed a cult following fueled by awkward moments from its reactions. A planned sequel, The Party, was paused after 2013 and later resumed in 2024.
