Why are fmv games not a bigger thing in VR?
Theres nothing more realistic right now than loading up a 5-8k porn video and having all that fidelity handled from a recording. But practically noone is incorporating videos into games.
You could crank out a good campaign worth of content from just a month of shooting, overlayed with a basic VR gameplay component and bob's your uncle. 
Id jump on this if i had a few grand to spare.
