"Super Mario Bros., both the original game and the many it spawned, has an almost intoxicating level of detail hidden inside its weird fiefdoms full of mushrooms, dinosaurs, turtles, and monarchs. Thirty years ago, that first game on the NES (or Famicom if you prefer) seemed mind-boggling in its intricacy. Hidden coin boxes! Warp pipes! Even the clouds in the sky were grinning at the player."
