Zork: Grand Inquisitor is a graphical adventure game, developed by Activision and released in 1997 for the IBM compatible PC and Macintosh (by MacPlay). It builds upon the Zork and Enchanter series of interactive fiction computer games originally released by Infocom. The cast includes Erick Avari, Dirk Benedict, and Rip Taylor. It is a 'point-and-click' game on 2 CD-ROMs (or one DVD that also includes Zork Nemesis) that allows the player to look around in a full circle of 360 degrees at each pre-rendered location (called 'Z-vision'). This visual freedom applies to the horizontal axis only; looking up and down is restricted, although possible in some locations.
