In reply to Zweetprot:
I can't imagine this training climbing at all, but I'm a big fan of VR and (quite obviously) a big fan of climbing.
VR games are pretty hard to sell without actually trying them - they frequently look dull and boring whereas chucking on the headset and playing them yourself can be a different thing entirely.
There are a few climbing VR games, the biggest budget probably being "The Climb":
Is it going to help your climbing? No.
Is it going to be any kind of replacement for getting out climbing? No.
Is it pretty fun all the same? Yep!
That said, it genuinely does give you a BIT of that feeling of exposure when you look down and all you can see is air.
The game posted doesn't look as high budget or polished as The Climb, but I imagine it could still be pretty fun. I can also imagine it appealing to climbers much in the same way I guess people that like footy play FIFA, so thanks for posting it op - I'll give it a go in a couple of weeks when it's out.
As an aside, VR can genuinely give a pretty decent work-out. Perhaps not in ways overly beneficial for climbing but after a couple of rounds of Beat Saber, or 30 minutes playing BoxVR I'm a sweaty mess.
