It might Push more Amiibos but it probably won't push hardware to a significant level. But it will help with the holidays though

I did see a kid playing with one when he and his mother came through the gas station i work at.

exactly 3,504 units

Nintendo wants to avoid looking childish. I dunno if this helps there image. Can you 5 or 6 year old even understand how to at Mario kart?

Don't act like it's a stupid question. I honestly think your response shows you know nothing about advertising. Obviously it will help sales in the long run. It's not like sales will increase next week but getting your name out there is never a bad thing. Keep in mind the PARENTS WITH MONEY will buy the system. Not the kids with the toy. Sigh...

Also guys don't take my comment as trolling. Def not meant to be trolling. More of a question about kids playing Mario kart

I doubt it, maybe a few thousand, but enough to increase the baseline? not really.

Most kids that age are still on the minecraft fad/trip.

It may increase recognition but as far as hardware sales go it is hard to say.

I dont think they do. They want to appeal to as many people as possible. Mario, Kirby, Pokemon, Donkey Kong and Pikmin all look childish, but they are very much enjoyed by gamers of all ages. If you can look past the graphics, youll find that they are fun games with pretty deep gameplay.

It might get MK8's name out there and even improve sales slightly, but don't expect anything too big!
