For those who prefer POV outdoor videos to riding in video games, you might want to try the seldom-mentioned BigRingVR. "Amazing HD video quality," as the site says, and over 400 videos. 30-day free trial, and $10/month, and less for yearly subscriptions.

I used BigRingVR years ago and have gone through a number of other subscription services since. I now use MyWhoosh. But BigRingVR looked great and worked well.
