In the most recent edition of Iwata Asks, Nintendo prez Satoru Iwata gathers up Takashi Tezuka and Toshihiko Nakago for a thorough discussion of their time with the company, the many projects they've worked on and their 25-year-long partnership with Shigeru Miyamoto. Let's break it down: Takashi Tezuka and Toshihiko Nakago both started at Nintendo around 1984, helping to shape everything from Balloon Fight to Super Mario Bros. These guys were part of the team that developed Super Mario Bros. and The Legend of Zelda -- at the same time. During the 10-page chat, a plethora of interesting tidbits are revealed about some of the game industry's most influential Nintendo titles. Did you know that Zelda was initially designed as a dungeon game without an overworld? Or, how about the revelation that World 1-1 was created last, after the rest of the levels in Super Mario Bros., and designed implicitly to teach the game to non-gamers? The chat even gets into the lurid sleeping arrangements of Miyamota-san and Nakago-san while on business trips for ExciteBike (spoiler: it's not that lurid).
