I have a quest 2, mainly I play Beat Saber (~$20 if I remember correctly, though it’s a really good investment and a really fun game), Gorilla Tag, Rec Room, SUPERHOT VR (also around $20 if I remember correctly, however this is arguably more fun than Beat Saber), and Arkio, which isn’t really a game but is still fun. YouTube VR is also kind of fun sometimes. As for things like Sidequest, I’ve only tried sideloading Minecraft VR, which was a very silly experience, however I would not recommend playing MCVR for longer periods of time because it gets very tiring and it’s pretty buggy.
