Konami releases Snake's Revenge, a sequel to the popular Metal Gear. Snake's Revenge was produced specifically for the North American and European markets, without the involvement of Hideo Kojima, the creator of Metal Gear. Kojima, who originally did not plan on producing a sequel to Metal Gear, is convinced to produce a proper sequel to the game in light of the intensely negative critical and fan reaction to Snake's Revenge. His sequel, Metal Gear 2: Solid Snake, is released later in the year. Though Solid Snake releases only in Japanese territories, many aspects of the game are incorporated into the next game in the series, Metal Gear Solid, which is a massive critical and commercial success not only in Japan but also in North America and Europe.
SEGA releases the R-360 arcade game, featuring the first 3D - 360° gameplay that physically rotated the real world player.
