Platform: Sega Saturn

The Saturn was going to have an attachment/follow-up console called the Sega Pluto, but only three prototypes were ever made and it never went to retail.

In 1992, after the failure of a deal to create a CD-ROM drive for the Super Nintendo Entertainment System, Sony approached Sega of America proposing that they collaborate on a next-generation CD-ROM console to compete with Nintendo. While Sega of America was open to the idea and even started testing the waters between the two companies by having each develop a handful of titles for the Sega CD, Sega of Japan shot down the concept. Consequently, Sony would reorient their efforts towards what would become the PlayStation, while Sega would develop their own next-gen console, the Sega Saturn, in-house. In an interview with Sega-16, Tom Kalinske cited the veto as a factor in his decision to step down as head of Sega of America.

In 2023, a 289-page PDF featuring official documents from Sega of America circa Spring 1996 was leaked online. Within this document were over 70 games planned for a North American Saturn release that never saw the light of day. These included:

• Ports of PC games (The Elder Scrolls: Arena, The 11th Hour, etc.)
• Multi-platform games (Grand Theft Auto, Lethal Enforcers, Wing Commander IV, etc).
• Japan-only Saturn games (Devil Summoner, Lunar: The Silver Star, Riglord Saga 2, etc.)
• European Saturn games (Destruction Derby, Discworld, Riven, etc.)
• Cancelled projects (Eternal Champions, Sonic X-treme, Virtua Fighter 3, etc.)
