Super Mario Bros. 2 (SMB2) 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. Also, the game was remade as part of the Super Mario All-Stars collection for the Super Nintendo, released on August 1, 1993 in North America, and December 16, 1993 in Europe. 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.
SMB2 did not begin life as a Mario title; instead, it is a remake of the Japanese Famicom Disk System title Yume Kojo: Doki Doki Panic (DDP). 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 to the western world at that time, instead releasing DDP with Mario characters under the "Super Mario Bros. 2" label. Japan later saw the western SMB2 release in 1992 under the title of "Super Mario USA" (???????USA(??????) ,Supa Mario Yu Esu E?). The Japanese version was released to the rest of the world as "Super Mario Bros.: The Lost Levels" as part of the Super Mario All-Stars collection for the Super NES in 1993.
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 SMB2 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.
