Maybe for the average consumer market, but there are lots of industries who currently use simulation software and are slowly moving to VR and away from expensive multi screen (very permanent) setups.

Take "Verification of Competence" activities used to on-board and train people who use specific plant/machinery. If you want to work on a mine driving a large truck, you'll usually have to do a virtual test to show your prospective employer that you can efficiently pilot $500,000 worth of machinery.

Health and safety training in complex plants. Run simulations on an immersive virtual model, rather than sitting at a computer screen.

Train driver training. Drivers need to do a particular number of trips to learn the route (accelerating and braking for turns, stations etc) this can be in field or virtual but required to ensure safety.
