Some YouTube streamers that I watch did a big run of VR games over the past year or so, and without exception they were gimmicky experiences that would have been better with a more conventional setup. Of course needing the equivalent of a GTX 1080 is a big barrier too.

My prediction is that when and if this new Half-Life game comes out, there won't be enough of a user-base actually using VR gear to sustain it; I hope that they have planned for that case and will release it as a normal PC shooter as well.
