Beat Saber is the most fun game I have ever played. No qualifiers. No shifty language. Nothing else is even in the same order of magnitude as Beat Saber. I dare to even call it a video game, because very few other games even possess the language to compete with it. The combat in FF7R is visceral, but you're not actually swinging Cloud's sword. The loop in Animal Crossing is entrancing, but it doesn't become your entire world like when you put a headset on. Even other VR games, which have that language they can use to tell their gameplay, often feel like the VR experience is bolted onto something which could, and maybe should, be non-VR. You often fight with the game; the game transplants you into a world, not just on a screen, but every degree surrounding you, yet you're limited in how you move, you're limited in how the game allows you to interact, nothing feels natural, and you soon adapt your actions with what the game wants.
I am solidly in the camp that, honestly, VR will not become a household item like a game console is. Even with headsets priced about at the level of a game console, like the Rift, the platform has too many downfalls.
Startlingly few games work well in VR. Even an experience like Half Life Alyx, the pinnacle of VR technology, feels like a shell of a game like Half Life 2. Its different. It can't tell a strong story, because players don't generally spend more than 30-90 minutes in VR at a time. It can't really innovate in puzzle design, because movement and viewport control is so heavy that it becomes tiring if you ask the player to do too much. The mechanics feel incredible. No one enters HL:A for the first time, loads that pistol, and doesn't have this HUGE GRIN on their face. But, its also a novelty; it wears off far too quickly once you begin realizing how many fundamentally core things Valve had to sacrifice to make the game work at all.
Nearly every game in VR is, bluntly, a tech demo. The platform is still figuring out if it is viable. Of the top selling VR games on Steam, #7 is a sim game which models a hyper-realistic anime girl, allowing you to mess with her clothes in a predictable anime way, and #10 is Skyrim. Of course, HL:A and Beat Saber are #1 and #2, but roughly this state is where VR was six years ago. It hasn't really evolved, and I'm not convinced HL:A was the catalyst I think Valve is hoping it is.
But, maybe I'm wrong. I will say this: There is no price you can pay for a VR headset that does not make Beat Saber worth it (within your means, of course). It is that good. I have an Index ($1000); beyond spending an hour or two in as many games as I can, 100% of my time is spent in Beat Saber, and I do not regret the purchase. Everything else VR has to offer is just icing. But this, a platform, does not make.
