VR is a cool idea, but it falls short on so many levels. It looks cool to go into a space that isn't there, but you always have issues with the mismatch of your surroundings and the VR world.
Playing Xing, and the recent Myst remake is awesome on desktop, but very tiresome on VR. The haptics are obviously not there and either you can't really walk where you need to go or you "teleport" around which feels strange. Overall its tiring mentally and physically.
