I agree that it isn't just passion, it is his full time job. He clearly has passion for it too, but you can't make a mod suite this insane on passion alone. This is years of consistent 100 hour work weeks. All dedicated to making these VR mods better than any VR port, or even "built for VR first" games.

And he drops support for the game as soon as asked. Which requires shutting down for a week to disentangle anything related to the one game specifically from the rest of the suite. I can't say he didn't complain, but not about the work, just that it didn't have to go this route, but it did go this route, so he does what he has to.

While the mod is behind payment, the payment is for his work and dedication. If he had to subsist on donations, he wouldn't be able to put 100 hours a week into it, he would need a job.

Again, the games are fully in their right to pull out, but they also admit that all he would need is their permission, they could choose to go that route, most do.
