I just had it for a month.
My review :
1) You can play all games using VR as normal non VR games will be displayed as virtual screen in front of you.
It wont be as high res as in HD or 4k but decent.
But made for VR games are so awesome, a new and amazing experience which are having more great titles to come. So the potential is growing.

2) Not all games needs move but some exclusively does such as Spiderman Homecoming demo, but with move, it makes the movement more natural and surreal!

3) Ps pro makes negligible enhancements on the loading speed and graphics ( based on online vids) but to average players, i dont think it matters at all. Ps pro advantage is on 4k tv use, not on PS VR.

By the way i bought my PSVR, move and ps4 eye separately from forumers as second hand only. Try looking in Carousel, i saw many good offers on PSVR bundles as well. Have fun bro! I enjoyed it!
Oh, some games can cause severe nausea motion sickness. Test it first if u can stand it
