Beat Saber is a great game with the mods of course. I mean base music gets you started but the tons of good music are in the mods. And Yes you will be well worn out at the end. 

I bought the PSVR, but it sits collecting dust. In the coming weeks my so will be out of the apartment for a bit, which is an excellent opportunity to try some again. I tend to like the shooter games with the AIM controller. But ideally I just get amazed in beautiful worlds. Something like Firewatch would be great to play in VR.

Currently have a HTC Vive and Oculus quest one and waiting for my Oculus quest 2 to come in. Favorite game would have to be Half life Alyx just cause visually nothing is better. Beat saber would be my second. Bought Valve index controllers but that was just to resale them for double. lol

I have a HTC Vive but honestly it's just been collecting dust for quite a while, used to screw around with Beat Saber quite a bit but the main issue is it's hard to play for extended period of times because it's a lot of moving around and flailing your arms. Might need to check out some shooters or other type of "less intense" VR games, once I get over the hurdle of re-calibrating it.
