While Rand Miller stated Cyan would not make another sequel to "Myst", Mattel (then the owner of the "Myst" franchise) offered the task of developing a sequel to several video game companies who created detailed story proposals and technology demonstrations. Presto Studios, makers of the "Journeyman Project" adventure games, was hired to develop "Myst III". Presto spent millions developing the game and used the studio's entire staff to complete the project, which took two and a half years to develop. Soon after "Myst III: Exile" was released, Presto was shut down, and "Exile" publisher Ubisoft developed the sequel, "Myst IV: Revelation", internally. Meanwhile, Cyan produced the spinoff title "", which included an aborted multiplayer component allowing players to cooperatively solve puzzles.
