Super Mario Bros. 2 is a platforming video game developed and published by Nintendo for the Nintendo Entertainment System video game console. It was released in North America in October 1988, in Europe on April 28, 1989 and in Japan on July 14, 1992. It was re-released on the Wii's Virtual Console in Europe, Australia and New Zealand on May 25 2007, and in North America on July 2, 2007.
Super Mario Bros. 2 did not begin life as a Super Mario Bros. title; it is a remake of the Japanese Famicom Disk System title Yume Kōjō: Doki Doki Panic. Nintendo's own sequel to Super Mario Bros. was released in Japan as Super Mario Bros. 2 in 1986. However, because of that game's extreme difficulty and its close similarity to the original game, Nintendo decided not to release it in the United States, instead releasing Yume Kōjō: Doki Doki Panic with Mario characters under the title of Super Mario Bros. 2. Japan later saw the modified release under the title of Super Mario USA.
Because it was not originally a Mario Bros. title, this game differs greatly from the original Super Mario Bros.. However, despite its status as the black sheep of the series , many elements from Super Mario Bros. 2 have become part of the Mario series canon and the repertoire of recurring elements. The game also sold well in its own right and was critically acclaimed at the time.
