Super Mario World is a 2D action-adventure platform game developed by
Nintendo R&D4 for the
Super Famicom in
1990 and the
Super Nintendo Entertainment System in
1991, with the
Nintendo Super System release coming out in the same year. It is a direct sequel to
Super Mario Bros. 3 and the sixth entry in the
Super Mario series. In Japan, it is recognized as the fifth. This game was one of two launch titles for the Super Famicom, the other being
F-Zero. In being a sequel,
Super Mario World retains many of the elements that debuted in
Super Mario Bros. 3, such as the
world map and
Koopaling boss fights, while introducing a large variety of new gameplay mechanics, such as an expanded and less linear world map and the ability to save the game. Introduced in
Super Mario World is
Mario's sidekick,
Yoshi (and
his species that shares his name), who serves as a playable mount for the Mario Bros. with his own unique abilities and gameplay style. The overall game was meant to be modeled after an action movie franchise, as can be inferred by the Japanese version of the Koopaling defeat scenes as well as the summary on the back of the Japanese box.
