Miyamoto explains to Iwata why he thought the original Zelda wasn't that unique.
In the latest entry of Nintendo's Iwata Asks column, the Nintendo President sat down with lead designer and producer Shigeru Miyamoto regarding his games and the recently released in Japan 3DS.
When Iwata asks how he makes it so that his games are the opposite of bland, Miyamoto explains that it is a misconception as he thought the original Legend of Zelda game for the NES was bland.
After the two of them exchange laughs at the comment, Miyamoto elaborates that he believed that at the time some of its elements, such as swords and magic, would never be featured in any major way. This is due to the fact that at the time of Zelda's release, movies such as "The Never Ending Story" showed fantastic elements common in the Zelda series, so the concept of a young boy finding as sword didn't seem as fantastic to the developer.
A translation of this part of the article is below.
Iwata: What you (Miyamoto-san) tend to make is usually the complete opposite of bland.

Miyamoto: Er, actually - that's a misconception
Iwata: It's a misconception?
Miyamoto: When I made Zelda it was totally bland. (laughs)
Iwata: (laughs)
Miyamoto: Stuff from that genre, I never thought it would be used in such a major way when I made the first Zelda. I mean, c'mon, back then a world of swords and magic was hardly major.
Iwata: Really?
Miyamoto: Sure, like "The Never Ending Story" was popular for a time. But seriously - this world of "Young man, take this sword and go"? You could definitely say that's bland.
