I remember when Half-Life 2 came out, and caused a similar push for new hardware purchases. Only then that push was for faster processors and graphics cards, particularly DirextX9 capable cards like those from ATI, at the time heavily promoted alongside the game. But those kinds of hardware purchases benefited more than just one game, and would ensure a great experience with all games throughout 2004 and beyond.
Imagine if the only thing that motivated Valve to create a new single-player game in the Half-Life franchise was the R-Zone, a horrible mid-90s headset made by Tiger Electronics that used shape-based LCD screens. The idea that "whatever motivates Valve to make a new Half-Life game is fine by me" is a pretty easy strain of logic to pick apart.
Now I'm not saying that VR is the same as the R-Zone, but a more appropriate example would be the Novint Falcon, a force-feedback 3D controller released in 2007. HL2 Episode 1 & 2 were actually patched to support it, but the idea was a peripheral separate from the core performance hardware of your PC that would enhance the immersion of your games. In essence, the same concept as VR, just with the latter being a lot more robust. Now imagine if following the support of the first two episodes, Episode 3 released with exclusive support for the Novint Falcon, dropping the keyboard and mouse. It doesn't help any other games and the barrier-to-entry is bulky expensive hardware that, aside from Valve's game, is novel and under-supported.
Valve wants this series to push the envelope, but I feel this time their free-spirited designers have revealed how out-of-touch they've become in the intervening decade plus, and the result is alienation through offshoot innovation rather than pushing baseline gaming technology that would benefit everyone. Again, if it were anything but Half-Life, it wouldn't feel like such a blight.
Would we all love to have the chance to experience it? Sure, but for average folks it's about as out-of-reach as it comes, and though I probably shouldn't mention it, the timing couldn't be more inappropriate given the new economic strain many are facing at this moment in time. It sort of comes off as the rich flexing in the face of an increasingly squeezed middle class, and the parallels to ageless classism problems are unavoidable.
