While I don't doubt this is debilitating for gamers and happens to many people, I wonder, do we really need another name for this?
Firstly, Virtual Simulator Sickness is redundant (simulations are always virtual, in that they aren't real -- they're simulations). It's a nit pick, but really, the TLAs get annoying after awhile.
Secondly, I can't help but wonder if this is really some new phenomena or not. I know a lot of people that get motion sickness from everything from driving, to boating, to watching TV, and they too suffer from even seeing games played from a fast-moving first-person perspective. Motion sickness, VSS -- call it what you will, but isn't this just one and the same?
Without any clear indication that this is somehow different from what we already call motion sickness, it seems like a waste of effort to persue it as a separate disorder. Much of the research already shows that VSS is and can be treated similarly to motion sickness.
On a separate note, I'm not sure that I follow the desire for game developers to make video games more approachable to people who experience VSS. If it's just the argument that too many games are shown from the first-person and not enough are or provide a third-person perspective, then fair enough, but for many games, it's not as simple as just using a different camera angle. For example, an FPS generally can't be played form a third-person perspective -- how would you aim?
I don't mean any offense, but perhaps people who experience VSS just need to avoid those situations. If you can change the game to prevent it, then great, but you can't expect to change the nature of the world. Some things only make sense from a first-person perspective.
