The entire Ultima series for sure. I think those were the first CRPGs I played. I loved Ultima: Underworld I & II, but I was never able to get Ultima VII: Pagan to run properly on my computer. (And, holy fuck, that was 30 years ago.)
But also The Elder Scrolls: Arena, TES: Daggerfall, TES: Battlespire, TES: Redguard, and TES: Morrowind. The first two TES games would be challenging to make, given that many of the areas were randomly generated, rather than being designed.
It depends on what you’re doing with it.
I use it solely for Ace XR, which is a dry-fire simulator/tracker. Ace XR is available solely for Meta Quest (2 & 3), so I didn’t really have many options. Unfortunately, I’m currently rehabbing a serious injury, and I am unable to practice.
For gaming? Not really. I like the PSVR2 headset more for that; it’s a better headset overall. I’m still working on getting it set up to work with my PC though. As other people have said, getting corrective lenses for a headset really makes them more enjoyable if you need glasses; it’s a pain in the ass to have to put in contacts when I want to use VR. For the Meta Quest specifically, and upgraded head band and spare battery (that also acts like a counterweight) is very nice to have.
