Rustam1990 Imho it's simply the nature of Western mainstream porn. It's about cutting expenses to maximize profit on mass-produced scenes because frankly most people watching mainstream porn just do it for a 10 min. wank - not watching a 90 min. cleverly planned out scene. It was just a matter of time before this mentality took over in mainstream VR after we had some years of fun. Now it's just autopilot and I doubt that's going to change.
It happened in 2D too but the difference is that in that market independent studios and creators filled in the void with actual creative scenes with longer stories, concepts, etc. and with large successes. We don't have that in VR - yet. The reason I can only speculate about but I think the issues are the market is to small and that VR/AR porn is nowhere near as easy as shooting a 2D scene. It requires know-how and expertise that aren't easily acquired. And it's expensive too.
