I got my PSVR last week and WipEout VR was one of the first things I tried. It blew my socks off. Incredible.
I still didn't bought it because I can get pretty sick with these kind of games, so if it was on PS+ it would be a good way to try it.
Also, I'm already blown away with Beat Saber, if you still didn't buy that, it's a damn must buy.
EDIT: I guess Onrush is cool, already play it on the X with game pass, happy more people get to try it. Will probably give SOMA a try, even though it's not my kind of game.
