Woah woah, slow down there partner. I'm only saying that Nintendo doesn't cater to the modern core gamers who play games like Assassins Creed/Halo/Uncharted/Call of Duty etc. they aim their games at families. The Zelda commercial shows it, the father played Zelda as a teenager in high school and now there's a game that he can play with his 6/8 year old son. I'm not making this is up, it's their marketing message! Here's an Iwata Asks on the subject:

Nintendo aims their games at families because those are buying the Wii right now, there's nothing bad or good about it it's simply an observation. The other observation is that Nintendo has said at E3 that the Wii U is designed for the core market but they have yet to develop or publish/secure for example a succesful online multiplayer shooter. Which is kinda strange since they were fairly quick to jump on the Monster Hunter-train in Japan which is aimed at a very specific group of core gamers.
As for the terms you might not like it but Nintendo is using them all the time. Saying that game systems had become too complex for newcomers and they wanted that group back into gaming as well. A noble effort that has certainly grown the market but it also meant that their own fanbase felt kinda left out during parts of the Wii's lifecycle. In fact the Wii U name is based on this, at E3 Reggie said that: 'some of you felt' (the core gamers in the audience) ' Wii is not for me' they revealed it as a system that would not only be used by families or in a multiplayer environment but would also offer deep and rich gameplay experiences for gamers mostly playing alone both online and offline. That's where the name comes from "Wii U" a "Wii for You".
Nintendo was also one of the first publishers who made packaging to show a difference between 'core' and 'casual' games with labels like Touch Generations! . It was made so people who were new to gaming knew what type of games they should buy.
So that's why I don't get why Nintendo fans feel I guess.. offended(?) or annoyed when this is brought up because in reality Nintendo actively split their product line in what they called 'core games', 'casual games' and 'bridge games' like Mario Kart.
