If I had a penny for every time someone said "The Wii U needs 3rd-party support!" Then I'd have enough money to buy (another) Wii U.

But that's because it's true! Mario and Zelda aren't the only things that will make people buy a Wii U, and many people (Like myself) want to see some new stuff as well... Or at least a new Metroid Prime.

I would propose a larger deal with Disney actually

- There will be a Nintendo Land section at all Disney parks that brings all the various Nintendo IP characters together in one amusement area.

- Disney gets rights to Nintendo IP for motion picture development including a live action Zelda trilogy, Mario characters in Wreck It Ralph sequels (which set up a standalone Mario CG spin-off movie), and other animated Nintendo IP.

- Deal for yearly Disney/Marvel games on Nintendo platforms, so Nintendo isn't stuck supporting their future platform on their own. Retro Studios could work on the Avengers or Guardians of the Galaxy, while expanded the second studio could work on whatever else they want. Exclusive Star Wars games could also be worked into the deal. 

That's the problem. Actually forgo the MP part and they just go with a long enjoyable adventure.

A story rich game with a solid gameplay would do the trick. Forget Halo.

No they didn't try this approach with the GC.  The GC was not easy for third parties to port games over to.  Having Nintendo exclusives and third party games all in one box would sell their next console.  

Your approach of making games based on movies will not do anything, there is already that stigma that movie based games are bad.  You don't even suggest how to make these games good, make them in house and cut development on their first party games?  Hire big, talented third party developers that would probably cost a fortune?

It was easy enough for the GameCube to have virtually all the same Western games as the PS2 and XBox did. GCN had Madden NFL, 007 Nightfire, Prince of Persia, Tony Hawk, Medal of Honor, NBA Street, SSX, Beyond Good & Evil, Timesplitters 2, NHL, etc. etc. All those games basically sold the worst on the GameCube anyway, third parties cannot get away from the fact that their games will sell less on Nintendo platforms because they have to compete with Nintendo's own IP. 

Nintendo fans just don't take to multiplats either. Wii U had multiplats it first year, no one bought any of them. 

The original Xbox also tried and failed, but M$ did not give up, that was the difference

The worst thing Nintendo can do is to try to appeal to a targeted audience or region, whether it be "west" or "east" or whatever. They are most successful when they get "everyone everywhere" to like their games.

Good on them, but at some point that's a table where all the chairs are taken. MS and Sony take up all the table, there's no room for Nintendo. Nintendo will just be a third wheel cheap imitation of Sony/MS without the willingness to take losses if push comes to shove and the competetion gets heated (MS has an endless bank roll). 

If MS wasn't in the industry or bailed out and it was just Sony for Nintendo to contend with, this would be a more viable option for Nintendo IMO. Two's company but three's a crowd. 

Marvel/Disney arguably has more worldwide appeal than Nintendo does. Marvel just happens to be the "it" company in the West right now, their IP print money and have the rare appeal of being equally appealling to kids to the most jaded teenager/adult. 

Like has been said, I think Nintendo is always going to be the "odd man out." I don't think they should bother trying to be more "western" since western companies are always going to have home-turf advantage when Nintendo goes head-to-head with them. Nintendo needs to carve out a new market for themselves just like they did with the NES, DS and Wii.

Maybe this means releasing something like the Fusion. That said, I honestly think that Nintendo needs to go back to what made them such a success in the NES days. In the 80's kids were growing up in front of televisions and up until that point all they could do with the TV was watch it. Nintendo took that existing technology and made it way more enjoyable by bringing games to the television.

Today, kids are growing up in front of Smart Phones and Tablets. If Nintendo can bring console gaming to the smartphone using the same idea as the Wii U gamepad's Off-TV play, I think there could be an untapped market here. Imagine buying an Iphone protector/case from Nintendo that comes with buttons and an analog stick and then being able to play a game with console graphics while at home or possibly on the train via wi-fi on your phone?

Maybe this is a crazy idea, but Nintendo has to branch out from the dedicated handheld/Television markets. Not only are these markets shrinking but Sony and Microsoft are just too good with the technology and the big budget studios to compete with directly. Nintendo has to innovate.
