You probably used all the currently available VR helmets, which one seemed the most promising?
Naturally, VR developers follow all the innovations and changes that are taking place in the market, all the innovations. I experiment with all the solutions on the market. but since its all pretty new its too early to say whats best.
I agree. It is interesting to try. But in order to make it interesting to play on an ongoing basis is much harder. I do not see it, neither with Oculus, nor with Samsung Gear VR, nor with PlayStation VR, nor with Cardboard.
