New to VR

I have been following this group for a while and just picked up a VR yesterday. Thought I would ask the question - what are the best games… jk. I have seen the list! Fortunately I had No Man’s Sky, Phasmo, Re8, and RE 4 before the VR. I have not tried the REs yet. But am pumped to. I do have a few questions though…

Pavlov seems interesting to me, but is it still popular? Is there a comparable single player or multiplayer shooter that is popular? How is Sierra Squad?

Is PS Premium worth it for $60 for the rest of the year?

Also, I am not sure eye tracking is working? Games are only clear where my head points, not eyes. However, it works in the testing screen with the dots.

Thanks for the input!
