Have you actually tried it for yourself Alex?
Yes Oberon, I've tried it. The small shop where I buy my games from has one available for a demo.
I played 3 games (about 30 minutes in total):
Hustle Kings,
Until Dawn Rush of Blood and
Drive Club. All three are VR native.
The wow factor is impressive, I admit. Expecially with race games I had my troubles to remain standing on my feet.
The visor is ergonomically very well projected, it's balanced and confortable. It also allows to wear headset and glasses meanwhile, which is good.
After some minutes though, visor & headset together begin to be heavy and it's not difficult to sweat so, inside the visor, the lenses steam up... lol.
By playing only 30 minutes I didn't notice anything wrong with my eyes, but I bet they would hurt or get dry or something, very soon.
The controller is still necessary to play then everything is just a videogame with a wide angle of vision, nothing more.
As I stated recently in other posts, this is not yet Virtual Reality as they call it. I will not buy it for sure, neither for me nor for my kids.
