Hairsational I just don't see it unless the had very amateur devs that learned coding on the spot. Their interactive features that separate them from other players include:
-Videos automatically load in sequence
-Changing positions during sex with a menu that cuts to specific times in the video (SLR has this already)
-Selecting from a dialogue option screen (point and click on a thing)
-Discovering items in the world, including the stationary women themselves (point in a direction from a stationary position and click a mapped zone)
I'm no VR app coder, but I've had to do some coding in my life and Im just not buying that this was a mountainous effort, more like something a junior comp sci major in college would do in their spare time.
