No. For much of my gaming life I've had two main systems; a gaming PC, and a Nintendo system.
Majority of your typical 'next generation' games I buy on PC. I get superior graphics, control options, usually online, mod community and tweaking. These pros vastly outweigh the cons of buying these games for what I consider inferior gaming platforms that do nothing my PC can do, only less.
I always buy Nintendo platforms, regardless of issues I have with them, because it's the only place I can get Nintendo games. Given Nintendo is one of my favourite developers, and I've gamed Nintendo games for as long as I can remember, to pass on a Nintendo system would be to pass on Metroid, Mario, Zelda, F-Zero, and countless other franchises that I hold very dear. As I've said before, I am bound to Nintendo systems regardless of what Nintendo does. They have me by the balls, for better or worse.
But even with these two systems, there is always a library of games I can get on neither, and that is where a third system fills the gaps. Last generation it was the PlayStation 2, this generation it is the PlayStation 3. I didn't get my PlayStation 3 until late last year because the console exclusive library just wasn't enticing enough. Now that I have it my library is still quite small, and surprisingly my favourite PlayStation 3 titles are also available on the Xbox 360.
Going in to next generation I will be buying a Wii U for sure, for the aforementioned reasons. But I'll also have my gaming PC. If a game comes out for both, I will be getting it on PC, for the superior gaming experience. There is always the chance I will double dip if the Wii U version gets some seriously interesting tweaks, changes or additions to accommodate motion controls and/or the touch pad, but they'd have to be pretty damn fantastic to warrant a second purchase. Then I'll no doubt get a PS4 down the line. As for games that bridge the two, if I don't own a PS4 right away (which I probably wont) and I can't get them on PC, I'd probably get those games on the Wii U, but again may double dip for the better looking version once I pick up a PS4.
Console gaming value to me is entirely hinged on the exclusive games. Despite the 360 and PS3 having great value for most gamers, and for good reasons, they by large don't have a lot of value to me (until now) because 90% of the 'must buy' titles are also on PC. That's why I'm not really interested in the Wii U being a port machine, or having strong third party support in the form of getting every bloody game that appears everywhere else. I love the exclusives, the quirky games, and the unique titles I cant get anywhere else. It's why I love the Wii.
Nintendo is lucky they make great games, because if they were only developing hardware and didn't have those great exclusives I'd struggle to think of a good reason to buy the hardware.
Granted, it won't be used very often, but it won't be as much of a pain in the ass for devs to do 1080p as on the 360.
Say that a developer decided to ignore the 3d on the 3ds. Could they use more of the systems power towards making it look better? Or does the 3d actually not require that much power
