In an interview in the new issue of Famitsu, Miyamoto was asked why Nintendo‘s IPs are enjoyed around the world.
Miyamoto replied that the key to a successful game isn’t looking at what’s trending and trying to capitalise on that, but starting with ideas that the developers personally find fun and working around them.
“People have long asked me, ‘why does a mustachioed middle-aged guy like Mario sell so well?’ and I always think, ‘that’s a bit rude, isn’t it?'” Miyamoto joked (via machine translation). “Well, I wonder the same thing myself – why did an older guy like this become a hit? But if you look at it simply, it’s because he was introduced alongside incredibly fun games.
Did you ever play Zelda: links awakening? Play that and tell me that isn't about someone's childhood spent by the sea. Play that without crying over a fucking 'game boy' game.
Edit: but I don't think he ever made out with a dream manifestation of a metaphor for a seagull.
