Games isn't exactly the best stress test for a windowing system. Most (if not all) run in full-screen mode and don't really use it much after the launch. And that's not what desktop computing is about. You want to run multiple programs, you want them to integrate with each other. But games don't need any of this.
> you want them to integrate with each other.
Do you? Not going to lie, I'm perfectly happy just using the apps I want to use and having none of them talk to each other. 90% of my use is covered by Vivaldi (browser stuff which is most stuff these days) and Kitty (Neovim, random TUIs and utilities). The few other apps I have are Steam, Krita and Blender, which are all worlds unto themselves and have no need to integrate with anything.
There is a "Desktop mode" that I, at least, use more than the handheld mode. Not sure if it's running Wayland though.
