Reckon you're right about gimmicks and motion control currently being very dissatisfactory and impractical. I also like to sit on my butt chillaxing when playing games, albeit I might be sat on a chair instead of a comfy sofa.
The history of gaming is littered with failed input devices. But I think there's a place for innovation but it's hard to make use of it right now if it adds to the hassle and detracts from what you said about just casual chilling and 'illin.

But, I do like the look of immersive VR gaming. There are a lot of applications for it so it will take off I'm sure. But for gaming, the FPS is where VR is at. We're a long way from the 80s when VR headsets were neck snappingly huge eyeball burning monstrosities but I expect we've a few years of refinement and technological development before they can be said to work without hassle.
