I don't believe what you just said about Nintendo at all. This forum is a place where gamers go right. Outside of here, in the wild, do most of your friends have a switch that they use? The few that i know with one got it for there kids. And not for the reason you said, i personally could give a fukk if my kid likes metroid. Kids actually like Nintendo just like everyone else, so every kid wants one just like every kid had to have a ds.
Im 6 kids deep, #7 is four months away. I just might be an expert on this particular topic but that's my opinion

Parents don't want there kids exposed to teenagers, or violent games so that is why Nintendo thrives today even when they are not innovating as well as they used to. They still innovate more than the competition does, so they are the default kid system. The adults who struggle to understand this come off as potential pedophiles imo. Not pointing any fingers...
