Super Mario Bros. 2

Super Mario Bros. 2 (Super Mario USA in Japan, and Super Mario Advance on the Game Boy Advance) is a platform game by Nintendo for the NES.

The game 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.

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 series canon and the repertoire of recurring elements. The game also sold well in its own right and was critically acclaimed at the time.

The Game Boy Advance version is largely identical to the Super Mario All-Stars version, with a sprinkling of new features such as hidden coins and a battle mode homage to the original Mario Bros. game (which was included in every Super Mario Advance title).
