Super Mario Bros. 2 Full Gameplay

Super Mario Bros. 2, released in Japan as Super Mario USA (スーパーマリオUSA Sūpā Mario USA?), is a video game released for the Nintendo Entertainment System. It was later re-released on the Super Mario All-Stars compilation for the Super Nintendo Entertainment System.

The game that became Super Mario Bros. 2 started as a prototype for a two-player vertically scrolling cooperative game, which was later named Yume Kōjō: Doki Doki Panic. After Nintendo of America discovered that the Japanese version of Super Mario Bros. 2 was very difficult by western standards and similar to its predecessor, Yume Kōjō: Doki Doki Panic was converted back as a sequel to Super Mario Bros. for release outside Japan.[1]

With that, the Japanese version of Super Mario Bros. 2 later arrived as Super Mario Bros.: The Lost Levels on the Super Mario All-Stars compilation. And for the Japanese market, Super Mario Bros. 2 in the west was released as Super Mario USA.
