High Quality Content by WIKIPEDIA articles! Super Mario Bros.: The Lost Levels, known in Japan as Super Mario Bros. 2 (????????????2, Supa Mario Burazazu Tsu?) or Super Mario Bros. 2: For Super Players, is a platforming video game developed and published by Nintendo for the Family Computer Disk System. First released in Japan on June 3, 1986, it is the direct sequel to the then-best-selling video game of all time, Super Mario Bros. The developers have stated it was not, in fact, the original planned sequel, which was a prototype game that was eventually originally released somewhat unfinished in Japan as Doki Doki Panic. Due to the other game's high difficulty and similarity to its predecessor, Nintendo of America chose instead to hire the Japanese developers to finish off and release this original designed "Mario 2" prototype, which has resulted in some confusion amongst fans as to which was "the real Mario 2", some siding with the former and others with the latter.
