In this video Shigeru Miyamoto and Takashi Tezuka discuss World 1-1, or the very first level in the very first Super Mario Bros. It’s fascinating how every element on the level is designed to introduce you to a mechanic of the game, or how Mario moves and jumps. This is interesting if you like Mario, but also important for any developer in any medium who is thinking about the NUX (new user experience) of their product. I sometimes joke that in WordPress we put people on the boss monster level the first time they enter the dashboard. There have been improvements but still so much to do to naturally introduce people to our interface.
