Bonus: "VR legs" have been shown to carry over into meatspace. As in, there are VR users reporting "I can read in the car for the first time!" But, it takes a lot of slow, careful build-up to do well.

Conversely, if someone has bad experiences and tries to power-through them anyway repeatedly, it can build up an aversion similar to a "bad tequila night" and ruin VR for that person permanently.

Thanks for making Doom! :)

Interesting info that I was not aware of. I guess I was just a casual player, not a developer like yourself doing it all day long (super-kudos btw - you changed the gaming world). All I remember about Wolfenstein and then Doom, is the wonder, the wow. I personally was amazed that this 3d rendering, basic as it was, was even possible, at the time. We were well before any 3d graphics acceleration. This was bog standard frame buffer VGA, or even, for Wolfenstein, CGA? Correct me if I'm wrong. Silicon Graphics workstations were super-exotic!

I suppose VR has a higher hurdle-rate because the nausea thing has been pre-telegraphed by early adopters of suboptimal beta tech. But I have no doubt that immersive technology is the future.
