VR is still a bit niche and only VRC actually offers an easy road to creating experiences - it's way easier to get novelty junkies on VRC to checkout a world than to try to sell or market a standalone experience. Probably easiest to just run a patreon at these levels than actually sell games, too.
Not the immersive metaworld thing that is so popular in fiction, but a real fun game that is not just about being VR.
VRChat has, I think, a more limited demographic than Beat Saber, and it is probably not where the future of VR is. I mean, it is cool, and I think it is here to stay (or if it doesn't, it will be replaced by something similar), but like Second Life today, I don't think it has much room for growth.
