Miyamoto, I agree and disagree this time. Most of what Miyamoto said are valid points. The fact that the says we need more children derives from the idea that children are the most creative as opposed to adults, and I know there are boundaries there as well but children aren't afraid to be different unless they've been told that it has to be done "this way" and ultimately, that shaves the creative block.
However, people are looking more and more to find other ways of experiencing stories other than film. Games offer an interactive way to enjoy stories. I understand Miyamoto, from a standpoint, but he seems a bit biased. As a game designer who develops games that have little to no story, with the exception of Zelda which isn't even all Miyamoto's doing. Games like Mario and Pikmin don't require such stories to be enjoyed as they're games that are enjoyed through playing it. Saying that wanting to create stories that have an impact is deprecated or not embraced is a little unsettling to me. People have stories that they want to tell and not always can they be expressed via jumping on shrooms and yelling "wa-hoo!". I feel very deeply about this because I want collaboratively make a game that is impactful sometime in the future while also maintaining core gameplay elements.
One thing that makes Mario so different, and for what I give Miyamoto and his teams respect, is that the gameplay is non-linear, and was non linear for the time that the games arrived. Joy was expressed through soaring and charming visuals. But, everyone has a story. To restrict that story to a specific type of media crushes the creative process. I'm not saying that Miyamoto has said this directly but I'd have to agree to disagree with the statement that is the title of this article.
