It's very well made. Amazing graphics for a VR game.
But the best thing about it is interactivity. It's clearly a leap forward from "Press E to interact".
You can grab and shake things. You can pinch things with your own fingers. You can throw things how you want. The physics engine, and the controllers with finger recognition and vibration feedback make this feel very cool and natural.
VR is like 3D TV a few years back .. don't see the point if it is not standard with a gaming console or the price point becomes more affordable < $199.
I'm not sure what qualifies as an "adventure game", but the Half Life games are more accurately described as a first person shooter with mild platforming and puzzles to solve.
This one isn't any different aside from the lack of platforming due to the VR constraint.
