There have been some other older adventure games that were conceived or in production, but that were never finished (from memory, there are more of course): Willy Beamish 2, 4th Journeyman Project, Master Lu: The Siberian Cipher. The lack of funding for Juniper Crescent was indeed sad, as it looked so great. There used to be a site with games that were never made. There is still
one for various platforms.
