Here’s a list of VR games I’d 1000% recommend:

• Half Life: Alyx
• I Expect you to Die (James Bond themed virtual escape rooms - 3 games in the series so far, all of them are good)
• Super Hot (slo-motion first person combat puzzle game)
• Beat Saber (a unique rhythm game)
• Pavlov (CS:GO but in VR with extensive modding support)

There are other good ones out there but that’s the list that justifies the headset to me.

Also there are some good VR ports of non-VR games out there such as Myst and The Talos Principle. Also there are some good Minecraft mods that add VR support (Java edition of course). Stay away from the Skyrim port though.
