Up until now I would have agreed with you, and this is coming from a die hard VR head, but HL Alyx is a total and utter game changer. So far the vast majority of VR shooter games seem to have started out being designed from a flat screen perspective and then had VR thrown at them - this mostly doesn't work well at all.
HL Alyx was designed from the ground up to be a VR game and by god does it show.
I do get where the VR naysayers are coming from - headsets are too bulky and uncomfortable, resolution too low, too demanding on hardware etc. Personally I can easily overlook these current shortcomings for the level of immersion that it gives me, but I do understand those who can't.
However the technology is still in a maturing process. Gen 2 devices are likely to be released within the next year to 18 months. Plus game devs are beginning to understand how to design specifically for VR, and are realising for the most part that you can't just take a flat game and throw VR at it.
Within 5 years VR will stand side by side with flat gaming and people will alternate depending on the game being played - not all games are suited to VR, and not all VR games will be meaningfully playable on flat screen. HMDs will become cheaper and lighter, and the graphics horsepower need to drive them will become more financially accessible - no more needing a $1000+ GPU for acceptable performance.
These are exciting times for us, the gamers.
