It's how I "gamed on Linux" for a couple years. Support is basically you and you alone. The dev for Looking Glass is active but the man isn't your personal tech assistant so often you're just doing A/B testing to make something work.
For me, I just didn't want to fiddle with my home desktop that much. I went back to Windows.
It does have it if all you want to do is develop, browse the web and similar things.
Including windows games into the things it needs to run without hassle is kinda unfair in my opinion, as that's pretty far from what this DE is used for regularly.
I went back to windows on my home pc because off games too, but my work environment with Ubuntu/regolith was significantly less painful to setup then the WSL hassles I had to jump through on windows before.
I'm still suffering with Linux for largely philosophical reasons at this point, but quite frankly if I wasn't such an opinionated nerd I'd just go to a normal Windows machine at this point.
