"The problem with the touchscreen and the Wii remote is that Nintendo didn't design some great game and then realize that they needed to make a new control method to achieve it. You can see that sort of design with the N64 where in the development of Super Mario 64 it became clear that they needed something other than a d-pad so the analog stick was added."
IanSane, if the world worked like you hoped, it would be ass-backwards.
The most profitable companies in the world do one of two things: provide a product or provide a platform. Google provides a platform. BP provides a product. Facebook provides a platform. Subway provides a product. Nintendo is in a unique situation where they provide both.
If necessity is the mother of all invention, then innovation is the conglomeration of inventions. Furthermore, creativity is how to wisely use those innovations.
Nintendo didn't think of Super Mario 64 then think about the technology they would need to play that game. In the business world, that never works. You are likely to end up with exorbitant R&D costs and a very narrow platform. Instead, Nintendo thought about the platform of how all 3D games would be played and what is necessary to make them work. Analogue sticks were already invented, so through innovation, they made the 64 controller and console what it was, i.e. a giant platform where both Mario and GoldenEye (a game that had to be unforeseen, but was creatively made) shined.
Those same principles are true today. Don't go into development thinking about a specific idea. Instead, think about widening your platform; adding utilities that broaden it, and stripping away those that lessen it.
Faced with a challenge of whether to let graphics be the main broadening tool for the platform after the gamecube, Nintendo decided they they did not want to fight for the same platform space with other companies. So instead they focused on a new controller. They scoured the world for technologies that could pertain to their market. There wasn't a specific game in mind, because there never is. Instead, they were looking for the chance to be innovative. And guess what? They found it. The Wii Remote, love it or hate it, changed the scope of every major videogame companies platform forever. All the sudden it wasn't about graphics anymore and being content with control design, it was about widening the platform on all fronts.
Nintendo deserves a lot of credit for that. Their game designers deserve a lot of credit for making the most of that platform from day one with Wii Sports. It was an obvious game, but it was done in a perfect style that drew in a number of new customers.
So now Nintendo is looking for another innovation to help broaden their platform and thus, their appeal. And I think they found it again. Streaming technologies, the ability to take your game away from your living room, broadens the platform of both game development and appeal. When used in tandem, it has even more power.
Did they have a specific game in mind before looking into streaming tech? Nope. Did they recognize the tech's innovative potential? Yes. Do they have an elite game development community who becomes ecstatic at the chance of being creative? Yes. Will they take these innovations and make them into a solid product for which people can use them creatively? That is the point; and not the other way around.
