This seems more like really bad game design ideas
You really should let the developers just surprise you instead of thinking about bad game design options .
Then you're back into the problem where developers have to spend a lot more money and time either porting to this weird gimmick, or going all in exclusively on it.
Developers are quite fond of being able to easily plop things across from PC to PS4 and Xbox One. Less work jumping through hoops, more returns. Hell, the similarity between VR platforms means people can count on easier porting too.
All Nintendo had to do this generation was hunker down, make some hybrid well powered system or very similar handheld and console offerings and deliver good content available across both. If this thing pans out, they've already found the way to fuck themselves with a wildly expensive gimmick just like the WiiU gamepad. Its just insanity.
Just as VR arrives to deliver a concave/360 degree view, Nintendo choose to focus on convex and all the limitations with that. I guess I shouldnt be surprised.
