Half-Life: Alyx on its own has justified my purchase several years ago of an Oculus Rift CV1! (but it's taken me far too long to get round to completing it)
The world is so immersive, combat is fun and the story is gripping throughout.

Two minor annoyances
1. Really need an option to skip the unlock puzzles, they don't add much to the experience when constantly repeated
2. Throwing grenades sometimes just results in dropping them by your feet, feels like the input needs to be a bit more generous (might also be linked to when framerate drops happen)

Well done Valve you made something very special here and showed how brilliant VR can be.
