vr games are expensive as forget. but if theres any games i would recommend spending money on its Beat Saber and H3VR (Hot Dogs, Horse Shoes & Hand Grenades)
beatsaber is probably the most fun ive ever had in vr. once you get good at it you can install a mod manager and play some hard songs that people make.
H3VR is like a weapon simulator. best gun play ive seen in any vr game with a HUGE selection of weapons. its a shame that theres no real goal in the game and its mostly just a forget around. they have 'game modes' but i really don't care for them. This game kinda has a learning curve but once you learn it its so much fun.
as far as any other games, Super Hot is fun but really short. GORN is really fun but also really short. also theres this one game called Climbey thats pretty cheap and fun.
