There's loads of options courtesy of apps like MirrorPlay.
And this is the Vision Pro not Vision. So the mainstream price will be significantly cheaper.
There are some launch 3D games but most are being built/ported right now.
(Similar to Bing where Bing Maps is worse than Apple Maps, but nobody reported on it because nobody remembers it exists.)
That's why it's called Vision Pro.
And Apple today added support for spatial personas allowing developers to create the experience you are talking about:

I believe the only way Apple will make that happen is a radical change in attitude toward developers. They would need to court developers of games and owners of content and negotiate -- generously -- on terms, instead of dictating terms and clinging to the 100% control and 30% revshare they feel so deserving of.
We'll see in a couple years if I'm right!
* Honestly though, still, even at that price, can you imagine most people being eager to add another almost-$2000 device to their lives that doesn't replace another one, unless the device does some serious life-improving stuff? And I don't see how the price gets any lower than that, even if Apple budged on margins which is very out of character.
Apple released a VR headset that you can't use to play video games or watch porn with, and priced it at ~2-6x the price of competitive hardware.
