Super Mario Bros. 2

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.

The American release of 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 original sequel to Super Mario Bros. was released in Japan 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. Japan later saw the modified release under the title of Super Mario USA.

Because it was not originally a Mario 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.
