Motion sims for vr in general are great, however, the problem you have is the cost. They cost enough that there are not enough people that own them for the devs to to take the time/cost to incorporate support.

If it wasn't for covid, I'd say there's plenty of VR cafes out there to consider supporting an inexpensive sim like the Yaw. This thing is looking to be in the 1-4k range, which is still coming in thousands less than those "9d VR simulator" Egg things they've got out there in malls and whatnot. But again, covid, so who knows now.

Most vr cafes have not done well. Even void had been shutting down experiences, and theirs was pretty great. For the simulators, it depends on how the integration is done. I believe yaw just requires basic tekelemtry output, which is fairly easy to incorporate, so that may see some adaptation. But, the fringe simulators that require their own distinct sdk integration just aren't worth it for the most part-theres too many of them with too little users.
