Has anyone actually read the article? He's only asking for a proper singleplayer campaign as they've focussed on the multiplayer part of the game.
Not really that much of an article, but the outcry in this thread is rather stupid.
The guy is speaking from a viewpoint of someone who already owns other consoles and wants something different to play on the Wii U and has the Wii U in the capacity of a secondary console which satisfies those needs.
That's exactly the opposite of the type of advice Nintendo needs really and exactly who not to listen to and the guy probably would see it as well if he wasn't so wrapped up the context of his own situation.
What Nintendo needs is the ideas to make the Wii U into a halfway primary console at least, something you could own without owning anything else and be satisfied - something which the Wii U miserably fails at. The author needs to pull his head out of his arse for one minute and actually look at the commercial landscape a little. This op-ed is junk and the guys opinion is junk.
