Zork III

In some ways, Zork III: The Dungeon Master is the original Myst clone. There is a sliding blocks puzzle and some mechanical puzzles, all in the context of little plot and lots of ambience. There are also some standard inventory based problems, and a few very strange people to deal with. As such, there is not much of a story to propel you through the dungeon, just your love of exploration.
