I did like Fallen Order. It’s not particularly challenging for the most part and it being compared to Dark Souls is overblown, but it definitely “gets” Star Wars.
I haven’t got around to playing it yet, but what you’ve described sounds a lot like The Witcher 3 for me.
Don’t get me wrong, I enjoyed it enough to finish pretty much everything (except all the Skellige question marks which thoroughly outstayed their welcome), and Hearts of Stone is better than Blood and Wine, but the gameplay was pretty flat throughout, and most of my enjoyment was in the cutscenes and dialogue and following threads to their inevitably grim conclusions. It’s not a game that I would ever replay.
If you have a solid gaming PC, yes. There is no immersion quite like VR. No amount of monitors will get you there.
It’s a bit of a faff each time you want to get it going (having to start the link each time), at least compared to a dedicated headset like the original Rift. The Quest 3 is a bit pricy, the 3S and 2 not so much. There’s a few decent exclusives for the 3 that aren’t even available on PC, so of the two I’d get the 3S.
Low framerate will make you dizzy. The resolution not so much. You will need a decent GPU.
Most VR games are fairly small and low budget affairs. The big exception is Half Life Alyx which is amazing. The game I come back to the most is VRChat, just for the massive number of worlds that people have made. It will help you get your VR legs over time.
The first is a bit rough. It got a remake with Black Mesa which used to be free, but I don’t think it is any more.
I’d honestly just start with 2. It’s a better game all round. You can always go back and play Black Mesa later if you like it.
If you have a VR headset and a decent rig, Half Life Alyx is well worth it. I’d definitely play HL2 plus Episodes 1 and 2 before heading into that one.
