Staff Interview - Sonic the Hedgehog (Unknown Japanese Magazine, March 1991)
From Sonic Retro
Staff Interview - Sonic the Hedgehog is a single page interview of three staff members of Sonic the Hedgehog in the March 1991 issue of an unknown Japanese magazine. The people being interviewed are Yuji Naka, Hirokazu Yasuhara and Naoto Oshima. This interview was later used in the japanese Sonic Jam strategy guide.
This is a small sum-up of the interview by G.Silver
The gist is that Yasuhara runs down the basic scenario--not too long ago, in the "Right Stuff"-esque past, there was a particular test pilot who was good at running, they called him "Sonic" (and it was written on the back of his jacket), yadayadayada. This story was forgotten in America, but some of the Sega staff recently came upon it, and so they made the game, Sonic the Hedgehog.
Then Ohshima (listed as Big Island, of course) interjects just as the story is getting good and says the story is, of course, completely made up, and Naka says (as if the topics are somehow related) that you can't play Sonic on a Super Famicom!
