Lol somebody didn't have a childhood did they
You're not one of those people who think Nintendo only caters to babies are you?
Your condescending and snide remarks aside, I loved Nintendo games and whatnot when I was a child, but mostly for handheld gaming. I loved my Game Boy Advance and DS games that I had growing up. Metroid Fusion was tons of fun, and still is for me. But I realized after a while that these little handheld games just didn't offer the fun that PC gaming can (and that I an already play all my old DS and GBA games on my tablet with an emulator anyway). Handheld gaming systems are such for a reason: To pass the time when you're in situations where you can't use an ordinary gaming console or computer. Once I grew older I realized there were better ways for me to pass the time when I was bored, such as watching Netflix on-the-go. That's a thousand times more fun than doing the same old stuff one has always done on a handheld.
The biggest killer to me using Nintendo consoles when I became a teenager was that there is practically no multiplayer internet community for like 95% of all nintendo games. I mean, sure, you can do the handheld-to-handheld wireless linking with friends but that cant even begin to compete with what you can do with PC games and emulators. I don't
need my nintendo handhelds any more. They're meant to be time passers, and there comes a point in every young teenager or child's life where their parents trust them enough to let them have a more advanced time-passing tool than a handheld gaming system. After all, nobody in their right mind would give a food-spill-prone, tantrum-throwing, "oops, i dropped it", nose-picking 7-year-old a Galaxy Tablet. They get him a nintendo DS instead. In short, as I became older and my options opened up, I realized that simply emulating my games on my tablet was the far more logical option as compared to spending hundreds of dollars on an exclusive gaming system that I would only be able to use to *gasp* play games on and nothing else of real value.
If nintendo made their next handheld with smartphone capabilities, I would perhaps be interested in buying it. But I am not going to throw my money away to elongate childhood playtimes when I already have all the tools to do such right on my own computer, phone, and tablet. We have reached a point now in our technological advancedness where we can have a mobile device that can perform all the functions of a Nintendo DS and also perform all the functions of an iPhone. Therefore logically, the only reason why handheld gaming systems still have any use is for giving young children a safe platform to entertain themselves on without all the risks that come with giving a child a smartphone (although, if I understand correctly, it is possible for children to have access to internet research with the 3DS's internet browser capabilities; scary thought).
Also no, nintendo does not and has never catered to babies. I've seen my 2-year-old niece try to play wii golf with a wii remote, but she failed miserably in the cutest fashion possible.
