The AUR is a great option. I’d argue that it can often be a better experience than upstream deb packages, because there is more oversight to how it is packaged.

For example, lots of vendors will give you a binary “installer,” which kinda does whatever it wants to your system. Packages in the AUR often abstract this to simply a package with raw files.

Additionally, there may be problems with a deb, even on Debian. Instead of restoring to hacks, the AUR build scripts often include patches and fixes to get things to work, and it’s built right into the package.

I’m not saying that Arch and the AUR is always better, but the level of control you have over what you’re installing, and the visibility and quick feedback loop you get while fixing things is invaluable, in my opinion.

If you want deb packages on arch, you can try use debian container through distrobox.

I’m just a casual gamer but I use Debian stable and I’ve had very few problems. I think a lot of people believe that Debian stable is too old to be usable but steam works flawlessly. At least in my experience.

Aur is not as scary as it seens. But I don’t really have any good advice for gaming.
