Are you sure that's because once you get used to it VR ceases to cause motion sickness, even in people who are prone to getting it from other sources, or is it because 'people active in VR regularly' are a self-selected group and those prone to motion sickness as a result of playing are highly unlikely to join? Because to me it reads like saying vertigo is extremely rare among rock climbers, and concluding that means rock climbing cures vertigo when the much more likely explanation is that people who get vertigo do not choose to take up rock climbing because of the risk of suffering vertigo. If you know of any studies or reports on the subject I'd love to read them. I don't see how the conclusion you're drawing relates the vertigo of rock climbing to what I'm talking about, I don't really know anything about rock climbing in real life other than cliff jumping into lakes. Because in my experience and several others', we don't get VR sickness from games we actively play; and when we do feel it, its not something we go back to because its considered poorly made. I can't see how a rock climber can get used to extreme heights or never get vertigo, but I don't know because I'm not a rock climber. I get a fun vertigo from rock climbing in VR, but I don't get VR sickness from every play session. I got a rift pretty early on and have studied other people's experiences in relation to my own, because its an interesting subject, whether by observation by showing my rift to others, relating through discussion our first time experiences and our adaptation over time, or reading online reviews and personal experiences on VR news related websites, discord, or watching reviews made on youtube videos, or listening to VR podcasts. People love discussing their VR experiences because they're very interesting. HTC, Oculus, and Valve are all researching VR sickness, finding solutions and incorporating them into their next gen VR headsets. I have not read any research papers on the subject, but they do discuss their findings openly. Its not just gaming VR companies that are studying the problem either, because there are training simulations for military practices, vehicle operations, medical procedures, and space flight training programs that cause VR sickness in some users, hindering their ability to learn and participate. Some people don't experience VR sickness, some people experience heavy VR sickness in certain experiences and none in others, some people experience VR sickness every time they put on a headset. Its variable. In my experience, I had a mild VR sickness every time I put on a headset, but each time I was able to go longer without the feeling kicking in until it just quit happening entirely. At first I was concerned and was ready to return it for my money back, but oculus reported on their public forum that it is a matter of adaptation and will lessen over time. Now, for me, it only happens in cheaply made roller-coaster experiences and terrible VR ports like Fallout 4. What I've personally found, and what many agree upon, is that the experiences that are the most immersive, the ones that are most like reality, don't cause VR sickness. For one example; I watched my brother in his first time with a VR headset get a very upset stomach from playing Shadow Legend, but then played Blade and Sorcery and didn't feel a single bit of VR sickness and played it for a longer period of time. I'm not at all saying that everyone who gets VR sickness should just get used to it. If you don't want to play VR games because of how it makes you feel then don't. I don't care. But should a vast amount of people miss out on great experiences because some will have a bad reaction? That's like saying, don't build an awesome roller coaster because someone will puke. Don't grow peanuts because someone is allergic. So, my entire point, is answer this question without regard to VR sickness. It is not a definite problem, and if it is a problem, its unlikely permanent. It is highly variable and depends on the user. Based upon Valve's Steam Survey, there's over a million monthly active VR headsets, so there's a hell of a lot of users that got over it. VR sickness is a more valid topic when applied to the question, "should you play a VR game?" The original poster indicated these conditions: "But it fully VR perspective like aiming spells and weapons, different locomotion options, 360 world viewing from headset, hand UI interactions (like grabbing something in your inventory) etc." which is the kind of gameplay that wouldn't cause VR Sickness.
