Having added some a bunch of games to my collection I wanted to give my thumbs up and down to some titles:
Absolutely get:
-Resident Evil 7
-Starblood Arena
-Rez Infinite
-Thumper
-SUPERHYPERCUBE
-Headmaster
-VR Worlds (if for no other reason than to have one VR thing you can show absolutely everyone: Ocean Decent)
-Batman Arkham VR
-Windlands (only if you don't get motion sickness)
-Tethered (if you like stategy games)
-Job Simulator (you need to set up your room a bit to get it to play well, and it starts to feel like a job more than fun, but the game is really charming and cool and really puts you into another reality)
-Call of Duty Jackal (it's free, and the best of the space shooters IMO)
-Joshua Bell VR (it's free and cool)
-Bound
-Here They Lie (this game is scary and wierd and sexy - you become a stripper in the game and go to a sex club)
-Until Dark Rush of Blood
-Volume
-Psychonauts In the Rhombus of Ruin (next to RE7, this game might have the best art on the console. It's a point-and-click adventure game using psychic powers. Made me forget how much I loved Psychonauts. Very slick, great writing, story and characters)
Maybe get:
-Wayward Sky (If you don't mind repetitive puzzles, it's quite cool)

-Tumble VR (it's good for what it is, but maybe a bit boring after you've played all the different types of puzzles once)
-Trackmania Turbo (if the whole game was in VR I was say absolutely get it, but there are only 40 VR levels)
Don't get:
-Pinball FX2 VR (it's the best videogame pinball I've ever played, however I wouldn't pay a quarter to play any of the three tables you get)
-Star Wars Battlefront VR mission (ok, maybe this is a controversial opinion, but I bought Star Wars Battlefront just for the VR mission and I didn't like it. The cockpit was glorious, but everything outside the ship looked so cheap. The background looked like a space mural that you would see in a children's kindergarten classroom; it looked fake and low poly and not like space at all IMO. If you are considering buying SW:B just for this, I would say don't. Download Call of Duty Jackall VR for free. The gameplay is better and it looks better IMO)
-Eagle Flight (another game that other have seemed to like. For me, the flying was really slow and boring, even holding boost. I wanted more of a thrill (especially after playing Windlands). Also, after my initial pass-over of the city, I just didn't find the city interesting or graphically impressive)
-Holoball (I wanted to like it but the game just felt cheap, not a quality game. There was no consistency to my swings. I could swing exactly the same and each time get a crazy different result. And my paddle would constantly bug out - instead of going straight out of my hand, sometimes it would go out at the wrong angle)
-Robinson: The Journey. (graphically the game was pretty but it has some major gameplay problems. The objectives weren't clear and even if you knew what to do, sometimes you couldn't do them until you triggered an audio cue in the level. For ex, I needed to repair a wind generator. The 4 pieces were strewn on the ground nearby. I wasn't able to levatate the pieces at all, until my bot said, ”hey, try levitating the pieces", which didn't happen until I had already walked and climbed all around the level about 5 times, then suddenly the bot said that, and I now had the ability to levitate the pieces. This kind of brokeness happened a lot for me)
-Fruit Ninja VR. (I was like "cool!" when I saw the swords in my hands, but unfortunately the fruit pops up so close to you that you don't have time to do anything but slice spazzily. The hit detection isn't great either IMO)
-Mortal Blitz (just felt like a cheap mobile game that I wouldn't play if it was free)
