Rhythm game that has you slicing blocks to the beat. There's a reason it's as popular as it is. It's a lot of fun and a good workout at the higher difficulties, and it's super easy to just jump into for a few minutes. It's definitely the VR game that I play most consistently.
A first-person squad based battle royale. I'm normally not a big fan of battle royales, but being in VR completely shakes the genre up. You can climb and glide all over the map which makes for fun encounters. Players are generally pretty social and friendly, which makes even hopping in with randos a good time usually. If you can find friends to squad up with though, even better -- and you'll probably make plenty before long.
It's sometimes nice to just kick back and relax in VR, and this is perfect for that. The environments are beautiful and all based on real world locations. This is my goto for when I just want to listen to some podcasts.
A very immersive WW1 themed aerial combat game. There's two campaigns, multiplayer, and plenty of control and realism options. Things can get pretty tense on the harder difficulty!
This table tennis game is shockingly realistic. The physics feel just spot on. The multiplayer is really fun, especially with friends. You don't even have to start a game, you can just hit the ball back and forth which makes it a great way to hang out in VR.
