Riven

Riven is a puzzle adventure game and the sequel to Myst. Developed by Cyan Worlds, it was initially published by Red Orb Entertainment, a division of Brøderbund. Riven was distributed on five compact discs and released on October 31, 1997, in North America; it was later released on a single DVD-ROM, with improved audio and a fourteen-minute "making-of" video. In addition to the PC versions, Riven has been ported to several other platforms, including the PlayStation, Sega Saturn, and most recently iOS-based devices. The story of Riven is set immediately after the events of Myst. Having been rescued from the efforts of his sons, the main non-player protagonist Atrus enlists the help of the player character to free his wife from his power-hungry father Gehn. Unlike Myst, which took place on several worlds known as Ages, linked together by special books, Riven takes place almost entirely on the Age of Riven, a world slowly falling apart due to Gehn's destructive rule. Development of Riven began soon after Myst became a success, and spanned more than three years.
