Super Mario Bros. 2 (NES)

Super Mario Bros. 2 is a 1988 video game developed and published by Nintendo for the Nintendo Entertainment System. After the smash hit Super Mario Bros. in 1985, Nintendo quickly released a minor adaptation of the original with advanced difficulty titled Super Mario Bros. 2, for its mature market in Japan in 1986. However, Nintendo of America found this sequel too similar to its predecessor, and its difficulty too frustrating for the nascent American market. This prompted a second Super Mario Bros. sequel based on Yume Kōjō: Doki Doki Panic. The characters, enemies, and themes in Doki Doki Panic have the mascots and theme of the festival, and were adapted into the Super Mario theme to make a Western Super Mario Bros. sequel.
Super Mario Bros. 2 was a resounding success, becoming the fifth-best-selling game on the NES, and was critically well-received for its design aspects and for differentiating the Super Mario series.
