(Super Mario Bros. came bundled with Duck Hunt on one cartridge, and that was included with many of the consoles sold, so actually sales figures of Super Mario Bros. alone is not possible to determine.)
Sales: 2.65 million (Japan only)
Genre: 2D Platform
Developer: Nintendo EAD
Super Mario Bros. 2 (the original) was only released in Japan, and was very similar to SMB but with harder levels. The SMB 2 that was released in North America was a modified version of Doki Doki Panic with Mario characters thrown in. This version was released as 'The Lost Levels' on future compilation packs and Wii Virtual Console.
