Something I’ve heard from every Mario developer I’ve ever spoken to over the years is this: Whenever you press a button, something fun should happen. Whenever your curious human mind goes, “I wonder what’s over there?,” the answer should be: Something fun. It can be something amusing, like the planet that looks like a Pokéball in Super Mario Galaxy, or something properly awe-inspiring, like when you look up at the ceiling of Peach’s Castle in Super Mario 64, directly into the sun at the center of its decorative mosaic, and you’re transported to a secret level where Mario soars through the clouds in a winged cap. Your curiosity should always be rewarded.
