Mario's Picross, one of the Game Boy's most important cult puzzle games and the title that introduced Nintendo's Picross series to Western players. What makes it especially distinctive is that, despite its quality and later cult status, it sold poorly enough outside Japan that its immediate sequels stayed Japan-exclusive for years. For collectors, the NOE version is also a nice regional piece because it represents Nintendo's original German-market release of a game that would only be fully appreciated internationally much later.
