VR industry is going to grow, there might be large enough user base in 5 to 6 years. Now there are only few thousand units of VR devices:
- 400k Vive
- 250k Oculus
- 900k PSVR
With conversion rate around 1% you wont get many units of your game sold.
Game changer will be when HMD will become standalone and price drops below 1k USD. It is still a bit expensive for regular customer.
Important thing is not to spend milions of dollars on making a single game. Make a great game with limited resources to make it profitable.
Here are all of my posts about Game Access.
