Hard Bullet is a game I'm looking at buying, aswell as The Walking Dead (the VR game). I don't know too much about these games yet though.
I already have Boneworks and it's honestly one of the best games ever, it's weird, very weird, but seriously a cool and fun experience in VR while still challenging.
VTOL VR is also pretty fun if you're into planes and such, it's quite easy to get the hang of controlling the aircraft in it, except for the helicopter DLC, that shit was too complicated for me. I believe it's recently been updated to support Multiplayer, I haven't tried it yet but i think that can be really cool.
PokerStars VR Is also really fun, it's pretty much Perpheads Casino but with more players, pretty fun/arcady interactions but it also allows you to play Poker or Blackjack more competitively.
Pavlov VR is another one of my favorite games ever. I always like playing TTT on it, it's basically CS:GO in VR but it's got the versatility of GMOD, allowing you to join modded servers etc with ease.
Lastly, a pretty gruesome game I've played is Blood Trail, it basically puts you in a kinda creepy arena where enemies will spawn around you which you gotta kill. It's kinda horiffic with the screaming and blood and dismemberment/deformations. But if you got anger issues it might be the game for you.
I literally love all these games and playing in VR is really cool expierence by default, It made me really dizzy in the start and kinda sick, but I got over that quickly by just playing in the mode which every game will tell you is only for experienced players, it's basically where you can press a button on the remote and move around. It'll make you sick because of motion sickness but you wont get used to it if you just teleport around. I really hope you take a look at these games and you enjoy them if you do play them. Sorry for the rant btw, I kinda just started typing away.
