How many years of VR gaming on how many other devices have produced how many Half-Life: Alyxs? And even Alyx was basically a vanity experiment designed to sell hardware. There simply isn't much content that has justified the medium yet. At a certain point I wonder if the future of VR gaming is just providing the biggest screen in your house to play your traditional games with a Bluetooth controller.

This seems strange, since so many folks love giant ultrawide screens for immersion whether playing console or PC and whether with controller or mouse+keyboard. They carry on how much immersion there is, and it's not nearly as visually immersed. So it seems less likely it's about the controller.

If they find the ultrawide immersive, and the controller is fine, why not AVP, since the "look around" control is just turn your head?

Do you not feel immersed when driving a car? You have fewer controls, and can't run around, you just sit there in your car seat, turn the wheel, turn your head, and gas and brake.
