Nicht direkt ein Textadventure, aber eventuell für den ein oder anderen hier interessant: Façade.
Zitat:
After more than six years of work, Michael Mateas and Andrew Stern have released their long-awaited one-act interactive drama Façade for free download. The system features a 3D environment and voice-acted, AI-driven characters, and has been a testbed for research in and development of natural language processing, drama management, and control of character behaviors. Research that went into the system has been documented in more than a dozen academic publications by Michael and Andrew, as well as in Michaels Carnegie Mellon University Ph.D. dissertation. A pre-release version of Façade made the finals in the 2004 Independent Games Festival, and one was also exhibited at ISEA 2004. The New York Times has called the system the future of video games.
