Looks good for sure and the HL vibe is there, but it screams to me that, creatively speaking, Valve is bankrupt in terms of storytelling.
It seems we're going back to the same events, over and over again, just viewed from a different perspective (which they already did back in the days with HL Opposing Force).
Will pass until it's either not on VR, or on a VR platform that is both very cheap and ubiquitous, hopefully in a few years from now.
Shame, I think Alyx deserved to have her own full blown sequel with HL3, and not constrained by VR.
