Speaking entirely personally, I thought at least Half Life Alyx's story worked on two levels. It was about freeing the gman as Alyx but gman sorta represented... Oh man, now I'm worried I can't remember the game well enough to communicate my original thoughts. I remember playing it and feeling like the gman represented the writers or creativity, a bigger picture concept or something that went meta. And if that was the case it felt like Valve creating a piece of art that said Alyx and VR have revitalized our desire to tell stories and GMAN is free again.

The moment they drop their new headset I'll buy it and play again just to relive the experience but I'd say I'm excited about Half Life because Valve makes A) good games B) they make solid diegetic games which I find to be kinda rare C) their games often feel like they came from a team of artists than just a team of coders. Maybe that's the polish or maybe that's the massive amount of testing I'm led to believe they do but when valve makes a new game it often feels like the guy who made Stanley Parable just made a new game - easy to recognize art because it's so good.
