The grafix and other things on the technical side will be amazing just given time, but what about the controls? I think it looks ridiculous when the prefered method of moving around in Skryim VR and Fallout 4 and even in Doom VR is by teleporting.
There's something wrong when many players prefer to zap-teleport forward instead of walking forward by pushing a key on the keyboard or a stick on a controller like we do in ordinary games and controllers. How can they make movement in VR game World comfortable and immersive?
