The first SML game sold so well that Nintendo went back to the drawing board and came up with the sequel. In 1992, Super Mario Land 2: 6 Golden Coins was released for the Game Boy and was also a smash hit. Mario returns in  the sequel that blends in elements of Super Mario Bros, captures the feel of Super Mario Bros 3 (classic NES game) and introduces a brand new villain, Wario (now a fan favorite and well known Nintendo character.) It's a great game that belonged in anyone's Game Boy collection.
