Super Mario World is a 2D action-adventure platform game and a launch title released for the Super Nintendo Entertainment System in 1990, developed by Nintendo EAD. 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. In being a sequel, the game 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.
