The Sega Master System, also known as the SG-1000 was released in 1985 in Japan and in 1986 in the United States. Original made to rival the Nintendo NES; the Sega Master System failed to make a huge impact in the US Gaming market.
During the dominance of the Nintendo NES, third party companies that made games for the NES were not allowed to make games for their competitors, including the Sega Master System. Due to the control over third party companies, Sega started to sell the Sega Master system in countries that Nintendo did not sell their system in, leaving Sega to do well in countries such as Germany, Australia, New Zealand, and a wildly successful market in Brazil.
One of the most inventive and unique accessories for Video Games was released for the Sega Master System, the Sega Scope 3D Glasses. The Sega Scope 3D Glasses used a shutter system to close the left and right lens to create a 3D effect and connected directly to the Sega Master System card port.
While the Master System was not as successful in the US as it was in other countries, it did have it share of great games such as: Phantasy Star, Wonderboy, the Alex Kidd series, Spellcaster, Golvellius, Strider, Psycho Fox and Ghouls & Ghosts. A large amount a great games where never released in the US such as: Ultima 4, Star Wars, Gauntlet, Micro Machines, Bubble Bobble, Forgotten Worlds, Sonic the Hedgehog 2, and even a port of Street Fighter 2.
