Half life Alex. I'm the only person I know IRL with a VR headset, so playing such an incredible and unique game feels like having an amazing dream that leaves you with intense euphoria , but knowing no one around you really cares as much about it as you.
I'm an early adopter of VR and there have been 2 memorable VR moments, the first time playing Elite Dangerous in VR with HOSAS and HL:A. But HL:A is the only VR game that I play through a couple of times a year.
The first time playing Elite with a headset was magical. Looking around my ship and while flying through space (or even just while sitting docked in the stations), and the spatial audio coupled with VR just put shivers down my spine. That engine whine chefs kiss
The only thing I didn't like about Half-life: Alyx is that I didn't feel like there was enough variety between the environments so it all blurred together and felt much shorter than it really was.
