It's going to be important for people to realize that HL:A literally represents the absolute best VR can offer right now across any platform or space. Like, if you got a VR *just* for Alyx, that's awesome, but now you need to make a controlled descent through a library that has a bunch of fucking awesome games, but nothing that will give you that same quality of experience you just got with HL:A. I'm sure people could make a list, but I'd consider:
1) Boneworks
2) The Walking Dead: Saints & Sinners
3) The Room VR
4) SuperHot VR
5) Beat Saber
In almost exactly that order, too. Each one of these games, especially Boneworks, will show you how VR has been one big experiment to reach HL:A, and how HL:A will almost certainly be the start of a new ladder of quality and refinement moving forward. I think it's an *incredible* time to be joining VR now, but people do need to realize that the current backlog of experiences is going to be all over the place in terms of quality, and how they solve various problems in VR.
