Lots of adults love Nintendo, but there is no question that their focus is more oriented for kids and teenagers than the market the other consoles go after. That doesn´t mean that its only for kids, but if I had to buy a present for my little kids for Christmas , it would be a switch, I guess playing Mario or Zelda is better for kids than playing The last of US or God of war right? And that translates into more sales if the machine is succesfull like the switch is. Also the portability helps, many parents would go and tell them, here you have it , go play to your room.
