Those VR's are fun, but they do have a warning on them for an age limit of 12 years old. The fear is that those little brains just aren't ready for the virtual reality experience. No studies to show danger or damage, but caution may be warrented. I figure a little play once in a while will be fine, but too much of anything is a bad idea. Besides, they make me sick.
A friend of mine took his son to a VR Gaming place. As the kids were playing , the manager made him try the "sample" that they have up front. It is simply a VR of opening a door and walking out on a beam to get a cake. My friend got to the end of the beam,picked up his cake and the guy says "now, step of the beam". My friend had a really hard time of doing that. He says the falling was so realistic, and when he "hit" the ground his knees kinda buckled, but he didn't actually fall. The manager told him that allot of people over the 35 will actually fall down when they hit the ground in VR. that would be me.
