I'm 6 hours into Half-life: Alyx and so far... it's kind of disappointing. It looks nicer and is much more polished than 95% of VR games, but it feels a bit shallow after the initial glamour fades and you're left with something that is an FPS that isn't a very good FPS.
The guns and combat feel great, but there's incredibly little of it, and you are always worried about ammo. I've searched and scrimped and conserved ammo left and right and still am usually low for at least 1 gun on normal, meanwhile I've left probably 20 syringes and untouched medbays behind. Some enemies you end up just walking around and not dealing with (armored headcrabs are so terribly dumb) because it's not worth the ammo.
The physics are fun except... you can only use them for sandbox stuff (which gets old after a bit), or distracting Barnacles or setting off Trip Wires, both of which you did in HL2. You lose from HL2 the ability to use physics stuff in combat (you can deflect / block some attacks with some objects but can't do any damage), and as far as I've seen none of the physics matters at all in action or really in the world at large.
If Doom Eternal was DMC wrapped in FPS controls, HL:A is definitely some kind of RE game wrapped in a Half-life skin, and to me at least it's worse for it. Just add more combine enemies to create more interesting fights and give me some goddamn ammo, I don't know why TWO major FPS follow ups in a row decided that heavily restricting ammo is what is fun about shooters.
