let's face it, Nintendo is stupid, if Wii had the gamer's support (3rd party & graphics) even partly it would have outsold Ps2 and still be selling
this gen they had the chance to recover 3rd party support and graphics with the WiiU, which they tried at first, but then suddenly they thought going with what gave them sales (casuals) would be the safest way, and hence, failed even more
next gen they have to be on par graphic-wise, and I believe their games are already unique enough not to mention that tablets or anything they can think of can always be an optional accessory, not all games were using motion controls anyway
don't mind my username, that was more than 10 years ago, I'm a different person now, amazing how people change ^_^
