I can't believe people are still doing the "Nintendo = kiddie" argument in 2014.
There's a big difference between Teletubbies, which clearly doesn't aim for a level of intelligence above what you'd expect for five-year-olds, and Nintendo's first-party content, which requires a much greater skill level than kids can generally manage.
One of my friends picked up a Wii U recently to play with his son. His son loves things like Super Mario 3D World but, being about six, he's not able to finish the game (pretty sure my friend told me he's made it to world 3 or thereabouts). That doesn't mean he can't enjoy it. It can also be enjoyed by people like his dad or myself, who are in our 30s and love the challenge of the later levels. Neither of us would have any interest in Teletubbies.
