I do agree with the first part of the article, he made a good picture about how Nintendo is (not) in touch with their costumers lately, about how they have screwed up with 3DS so far. But I do not agree to the rest of the article. He is generalizing way too much, he is assuming every Nintendo user wants the same thing also he is not even considering competition.
He basically says GC and N64 failed because they were different from how customers define Nintendo
"People have the expectation of buying a Nintendo product and still be enjoying it decades later. People associate Nintendo with the arcade side of games from platformers and action games."
So MK64 ,Excitebike64, Waverace, Starfox64, F.zero X, 1080°, Smash Bros were not arcade games? Mario64, OoT, Majora , Paper Mario, Smash Bros were not the kind of games you colud still enjoy a decade later?
The thing is competition matters, it's not only about Nintendo. If N64 wasn't succesfull it's because most consumers felt they had a better alternative with Ps1. Nintendo did a bad job with N64 but not on their own software side. They screwed up with cartridges, losing most of their jp 3rd party support also Sony had a better marketing and better logistics. Sony hardware and software was better distributed. I remember in those days I could find N64 games only in a few stores and they were ultra-expansive. Another example: Ps1 games were translated in many languages as opposed to N64 games which were generally only in english/french/german.
To continue, according to article Nintendo pushed to make more "mature" games on Gamecube but it didn't work because its customers wanted it to be family friendly.
I have quite different memories of those days. Like Ps2 and Xbox having all mature games, and GC having only Metroid Prime (which can hardly be considered an M-rated game) , Resident Evil and Eternal Darkness. The rest of the time Nintendo made games like Smash Bros, Sunshine, Pikmin, Double Dash, a dozen of Mario sports/party etc.etc.
If mature games didn't work on GC it wasn't because of its users wanting it to be family friendly, it was simply because GC was out of competition with M-rated games. For every M-rated game on GC there were 10 games on Ps2 or Xbox. If you were interested in M-rated games there was no reason to buy a GC. To make things worse Nintendo made the console and the gamepad look toyish, so that costumers couldn't even by mistake associate the GC with M-rated games.
Then he talks about DS success. basically DS became successful when Nintendo started ignoring the touch-screen to shift attention to arcade games like NSMBW and MKDS. In this way "The DS began to be how consumers define Nintendo".
Really? If you sum up how much those 2 games sold you have 48million units (according to VGChartz). This means (in the unlikely case no one has bought both games) that 48m out of 148m DS users own one of those games. What about the other 100m?
What I mean is he can't generalize so much, not every Nintendo costumers have the same definition of Nintendo also lots of DS users bought a Nintendo product for the first time, they had no definition of Nintendo to begin with. DS became their own definition of Nintendo. My mother have always hated videogames and didn't know anything about them. Surprisingly, she actually started playing DS, later she got its own as a gift and at the end she bought more DS games than me and never touched Super Mario or Mario Kart. Does he think me and my mother have the same definition of Nintendo?
The same logic applies to Wii. "The Wii was what consumers tought of Nintendo" . "In the consumers eyes the Wii wasn't new so much[...] Wii Sports Tennis was nothing more than a motion controlled version of PONG" . Not really, a huge part of Wii buyers were playing games for the first time, in their eyes Wii Sports was actually something new and different, most of em probably didn't even know what PONG is. Even in this case he can't talk of a pre-existing idea of what Nintendo is or should be.
I don't undertand what is this article suggesting exactly? Nintendo should stop innovating and making new consoles only to start releasing a Super Mario or a Wii Sports game every year? I don't think this would work in the long term. Customer satisfaction is needed to make users loyal in the long term; games like SMB, Wiiports, MK or Smash Bros are excellent but are not enough to satisfy everyone. If they want to keep every customer satiasfied (not only protion of them) they will have offer as many kinds of games and genres as possible.
The article calls WiiU a failure already even tough we don't know exactly what games Nintendo is developing for it. From what I know now the only clear thing is that WiiU is made with the attempt to gather as much 3rd party games as possible and that's the only way to offer a great variety of games. I'll decide if the WiiU is a disappointment when I'll see what kind of software it will get from both Nintendo and 3rd parties.
