I think people need to stop expecting good third party support for nintendo home consoles, period.
They've had what, 3 generations of consoles with little to no industry backing.
It's been at least 15 years, guys.
If your primary reason for buying Nintendo home hardware is NOT for nintendo 1st party games and the occasional quality 3rd party exclusive here and there -then you're doing it wrong.
Nintendo has to prove to everyone that their home systems are healthy markets for the majority of 3rd party publishers' serious efforts. Nintendo and it's fans shouldn't simply expect that support 'just because'.
Microsoft has earned the benefit of the doubt in this area. so too have sony. and so too, will nintendo have to prove themselves.
That said, i disagree completely with the notion that this is somehow a bad thing. Having the ability to sustain your own platform on the strength of your own internal efforts ALONE, is an absolutely HUGE ability to have as a hardware manufacturer.
The Nintendo 64 sold over 36 million units while it was on the market on the backs of nintendo's (and rare's) games alone. The Gamecube (their lowest selling home console) sold over 23 million WW because of nintendo developed games, and the wii over 90 million.
Yes they took advantage of the motion control boom with that last one, but they sold that concept with nintendo developed games. They sold that concept so well, that everybody else followed suit to some degree.
I have serious doubts Microsoft & Sony could replicate those numbers on the back of their own internally developed titles alone. Can anyone here even imagine what an xbox or playstation home system would be like without the 3rd party support they currently receive?
That's not to say they don't make incredible games. Sony for example, have an amazing 1st party dev team. However their games don't sell playstations the way nintendo games sell nintendo hardware.
That said, Nintendo will never be able to sell as many consoles as Microsoft or Sony without the 3rd party backing that they they get, but still... a minimum of 23 million on the strength of internally developed games -of which aren't even consistently released throughout the lifespan of a system. I think that's pretty impressive.
