Super Mario Bros. 2 (Japan)

Super Mario Bros. 2 is a sequel to Super Mario Bros released on June 3, 1986. Unlike its predecessor, it no longer has 2 player mode (you have to choose either Mario or Luigi). Has new enemies (mostly palette swapped), backward warp zones, winds, and poisonous mushrooms. Due to the game's difficulty, this game was not released in the United States until Super Mario All-Stars known as "Super Mario Bros.: The Lost Levels" outside of Japan.
