Pephaps a bit off topic but here's my two cents.
I think People really need to face up to the fact that Nintendo hasn't Changed at all! People like to believe that Nintendo was Better back in the "old days" But they're are exactly the same. People have always been baffled or taken a back by their controllers; just look at game controllers pre-nes. Even the Snes contoller confused people cause it had like a MILLION BUTTONS at the time.
Nintendo has always made stupid and arrogant decisions about their hardware that turned off developers. From the lockout chips on the nes they purposely made scarce, to the N64 using Cartridges. Nintendo has always made family friendly stuff with rare exceptions like Metriod, Eternal Darkness, and Funding Bayonetta 2.
And Nintendo's games have always been adored by critics, not universally but that's a given. Nintendo's games are mostly likely to be reviewed positively and pretty much always sell really well.
The only thing that has changed about Nintendo are people's overall opinion about them and their games. Nintendo as a company has not changed, for everything they do that's right they do something else wrong. If you feel that they have change it is because you have changed.
Take off the rose colored glasses.
But remember one thing and one thing that is very important, The industry needs Nintendo. With both of the other platforms saturated with "Mature" Games they leave a very large hole. By not changing Nintendo is Very Different then the other two.
They will continue to make light heated and fun games, they will continue to make funky hardware, and people will continue to adore them for it.
Regardless of how you feel about Nintendo home consoles post-GameCube one thing is constant, your experience on a Nintendo console will be fundamentally different then the other platforms. Whether or not that's a good thing or a bad thing is for you to decide as a consumer but that's why I say owning a Nintendo console is always worth it. The rest of the industry is converging to the same place while Nintendo remains an outlier by barely moving in some other direction.
