I think VR is in a unique position where the lowest common denominator will rise pretty quickly - or more quickly than for other types of hardware release, at least. The impact of motion controls in particular can't be overstated, and given that all the high-end VR platforms will have their own dedicated motion controllers before the end of the year (following the release of Oculus Touch, PS Move for PSVR, and now Google's Daydream will have a motion controller too), I think most devs will move to make those the default control option in short order. That's certainly where our thinking is at, at least.
FWIW, we just released
a second BTS video for The Assembly, this time focusing on the game's visuals and 3D audio, and featuring some areas of the game we haven't shown before.
