I personally feel like any magic that Nintendo had in the past is lost and they need to turn it over to a new generation of developers to get any of the magic back. That's my opinion. Nintendo is a little too stoic for today's worldwide gaming market.
I've played enough recent Nintendo games to know they still have the magic. The Fire Emblem games, Legend of Zelda: A Link Between Worlds, Super Smash Bros Wii U/3DS, the Pokemon games, etc. They just need a better home console platform than the Wii U to draw players, and developers, in.
Anyone that think Nintendo are a true gaming company need their head check. Nintendo is all about gimmick instead of the true game experience. Sure they were some of the first but so was Sega and still to this day produce "games" not "gimmick".
The NX or whatever it call should be more powerful than the PS4 and X1.
You might call it gimmicks, but in their drive to innovate on the hardware side, Nintendo has given us:
--The D-pad. (NES)
--Battery backed up cartridges, enabling save games on consoles (Legend of Zelda on NES)
--Shoulder buttons (SNES)
--Analog thumb sticks (N64)
--Wireless controllers (Wavebird for Gamecube)
--Touch screen controls (the DS got to it years before Apple did. And no, the Tiger Game.com does invalidate Nintendo actually pushing the technology)
--Glasses-free 3D (As a 3DS user I will defend this as awesome in games that use it well, such as Super Mario 3D Land or Legend of Zelda: A Link Between Worlds. And the New 3DS' face tracking technology addressed the issue many people had with having to be perfectly positioned.)
That's just off the top of my head, I'm sure I could find more if I dug deeper. The modern game experience would be a very different thing if it wasn't for Nintendo constantly looking for new ways to play games. Sure, they've had some misfires. The Virtual Boy. The Nintendo 64's weird three-grip controller. The Wii U. But those misfires do not mean that Nintendo should stop looking for the next big innovation in gaming.
And you really shouldn't be suggesting that other people should be getting their heads checked.
