I could absolutely see all three of these games work with VR... Fallout 4 IS getting VR, but only on PC, so unless they've got some exclusive shit going on, I can't see why they wouldn't at least think about bringing it to PSVR, the other games could easily just get patched since they're just walking simulators.
I think any sort of walking simulators should offer a VR experience too, since they're short games as it is, and having the option would probably entice more people to try them out.
Y'know what I'd like to see in VR? Flower. It's a simple game, works perfectly with motion controls (The controller of course), and I think being able to look around, as if you're surrounded by flying petals or breezing through the grass, could be quite the experience.
As for bigger games that might work with VR, I mean racing games are sort of a given, they tend to get good reviews from people who have tried VR, so more of that would be good I suppose. And more FPS games for sure, as long as they get the pacing properly, don't want anything too fast to cause motion sickness as you've said, but I've heard Farpoint is really great, so more of that would be welcome too, lol.
How about a new Time Crisis game in VR? Since they're on rails and have the step cover, you could actually move behind cover yourself which would make it more interactive.
There's so many possibilities really for games that would work really well in VR, like RTS games would be, in my opinion anyway, incredible with VR, using the Move controllers to, well, move units, lol, and you could crouch down or lean in to get a good close up view of the action too!
tl;dr I have too many ideas, lol.
Yes, Flower would be a perfect fit. I think we're moving into the second phase of VR and Skyrim/RE are the testers. Most of the launch games were shorter experiences and I don't think that was anything to do with doubt from developers but rather a mandate to 'acclimatise' people to the experience first.
The PS5 Exists.
