So if you ran Nintendo what would you do different with the Wii U? I think the Wii U is a good system that Nintendo has completely failed. Launch Titles (or at least first year games) should have been a new Mario Kart, a Metroid game, a proper new Zelda game, and a console Pokemon game. A Pokemon game would undoubtedly insure the success of the system. I know if I had money at the time I would have bought a Wii U to play a console Pokemon game. Then again I'm already planning on buying one.
I definitely wouldn't release Super Smash Bros at launch or even in the first year. It's definitely a second year game that would ensure the success of the system. Then there would have needed to be a new Starfox game this year. Starfox is still a popular franchise and it really puzzles me why Nintendo is taking so long to put out a new one or even say whether they will.
I also would not have made the Wii U so expensive. I think somewhere between $200-$250 would be a good price. That way Nintendo is still making a profit. As they said last year, the console only costs $150 to make. $100 for the gamepad and $50 for the system itself.
I definitely think a proper controller should have been released with it as well. But of course none of the above matters if the system is actually marketed well. I don't watch much TV and generally pay attention to commercials but I've only seen Wii U commercials a few times. I think Marketing is where Nintendo really screwed the pooch. Plus the name Wii U has caused so much confusion. They should have just called it the Revolution. It was an awesome codename for the Wii and it should be the Wii U's actual name.
