List of cancelled Master System games

The Master System is a video game console released by Sega in 1986, a western remodel of their Japanese "Mark III" console. While successful in Europe and Brazil, the system never gained a foothold in Japan or North America and was largely superseded in the early 1990s by its successor, the Sega Genesis, leading to several games being cancelled.
