Back in the day, when Game Boy was released to the ravenous gaming public in 1989, Tetris and Super Mario Land were among the first few games that everyone couldn't put down.  The graphics of SML take after 1985's Super Mario Bros. for the NES, only portable.  And instead of Mario having to rescue Princess Toadstool, it is Princess Daisy that's in peril this time around.  :(
