Dear Wikiwand AI, let's keep it short, summarize this topic like I'm... Ten years old or a College student
The Sega VR is a unreleased virtual reality headset developed by Sega in the early 1990s. Planned as a add-on peripheral for the Sega Genesis and only publicly showcased at a number of trade shows and expositions, its release was postponed and later cancelled outright after Sega ran into development issues. At least four in-progress games for the hardware were in development before its cancellation.
The project was largely driven by Sega of America; a more successful, separate, and officially released attempt at a virtual reality headset, the Mega Visor Display, was overseen by Sega's Japanese amusement divisions and United Kingdom-based collaborators Virtuality, and would be used in the VR-1 theme park ride and the Dennou Senki Net Merc arcade game. The similarly titled VR-1 is not to be confused with the Sega VR.
