sort by rating or release date if you wanna pick up some cheap good or new stuff. 
out of these Squadrons and PCars 3 are AAAA if you're into those kinds of games. Squadrons is good if you have hotas. 
No Man's Sky is also amazing in vr. 
I didn't look to see if any VR tools were on sale like xsoverlay, and this list won't show you tools, only games for some reason.
