I tried one of these VR setups down in Disney World a few years back. Having something on my head wasn't what bothered me - I got a seriously bad case of motion sickness and had to get out of the thing before it was over. Cold sweats, headache, nausea, dizziness, weak-knees, all that. Until they figure out a way to overcome the visual incongruity with what the rest of the body is feeling externally, I don't expect I will ever use VR again. Hell, there are some XBox games that give me motion sickness. I remember Left 4 Dead was particularly bad in that regard. However, other FPS games like Skyrim, Battlefield 2, Call of Duty...never had a problem. I don't get it.
