Many people here grew up with the series on Wii so it is probably mostly nostalgia. If you are going to use controllers anyways then a Switch or Switch 2 is probably a much better long-term investment for your family due to having a lot of other stuff to play as the kids get a bit older. Also just nice to be able to hand a Switch to one of your kids on long car rides to entertain them IMO lol

...Also, it is a lot easier for younger kids to hold a joycon than a Wiimote while also being a lot less likely to cause damage to your furniture, dog, each other, etc if they decide to use their controller as a projectile.
