There's not much more to say in my recommendation of Half-Life: Alyx other than this was one of the most remarkable gaming experiences of my life. I love Half-Life to begin with, but I cannot stress enough how transcendent this game is. The barrier to entry is high being a VR only game, and the tech sometimes doesn't match up with the experience (especially with the Oculus Quest 2, which is less than stellar in link mode), and you'll be left disappointed with every other VR experience after Alyx, but it's all worth it. My highest recommendation.
