Well I can't express an opinion from anyone else point of view now can I?
What I will say is time will tell, you say yay, I say nay, so it looks like some people will manage with it..non smokers, people who don't need to drink tea or anything else, you see we first have to actually decide what "play time" is, I would suggest that if the headset is removed once for any reason then the time is reset, my guess is our friend here played 3 hrs but probably did take the headset off at some point for some reason even if that was to scratch an itchy eyelid... which yes that does happen too.
No, but you were expressing it as if it would/should apply to everyone else... that was your mistake!
Personally I think VR hardware and software should be designed with breaks in mind - e.g. I would like to take off the Rift when I get to trading/mission screens in ED and for the game to automatically snap out of Rift mode on my main monitor and present the screen in normal 2D mode. In an ideal world anyway. So I sort of agree with you that breaks should be considered for those people that need them, but not all do, or will of course.
