I think it shows the kind of world difference between 'gamers' and 'people who buy switch'. There's clearly some overlap, but Switch (and Wii before that) appeals to non-gamers in a way people in the gaming bubble can't comprehend.
I was more referring to the fact that my grandma who has never played a video game in her life, has still heard of Mario. Zelda has been around almost as long, and is almost as culturally relevant to non-gamers. Or Pokemon. Or Donkey King. This is culturally significant IP we're talking about, gamer or not.
Not really. Since 1986 there have been literally dozens of Zelda titles released. This would be equivalent to someone saying that they had never heard of Star Wars or Microsoft Office.
