There are a lot of third-party Linux apps built with GTK4/Libadwaita. If you just to to https://flathub.org and click on random apps a lot of them will use GTK.

I would recommend taking a look at Flatpak

flathub flatpak format apps/games for linux desktop, does not require any specific linux distribution just that flatpak is present on the system.

Which X clients are these? You didn't name any so let's just look at some of the popular and recent flathub apps: https://flathub.org/

I see a lot of games, chat apps, text editors, photo apps, office apps. These all will work fine in XWayland and XQuartz. But also, it's relatively easy to get them running on Wayland natively.

If you're worried about the potential of breaking things, I'd pick the Fedora Kinoite distro. Up to date gaming support, stable and extremely difficult to break. Install apps from Flathub using the built-in Discover software store and go nuts.

You can go on flathub.org to found many other apps you wish to install.

8. Go to https://flathub.org/ and install other useful software.

9. Install an office suite (for example, https://www.freeoffice.com/en/)

For games, Lutris and Steam are your friends.

I only really play single player, but I have run into this too. This is a great resource to keep track of progress - https://areweanticheatyet.com/

It varies by game. https://areweanticheatyet.com/ is an interesting resource for that because they also track announcements by developers about whether or not linux support is eventually planned.

AFAIK the games that don't work are more modern, competetive games that use Anticheat. https://areweanticheatyet.com/ is a good resource to see the status of your game.

It is game by game basis. Use this guide to see if the game you play is supported or not.

The only caveat to that is online games with anti-cheat. EAC and BattlEye both support Linux but requires studios to tick a box, many of which refuse. Any kernel-layer AC that doesn't have a userspace component will not run on Linux. Can see a list of games and their AC support here.

> except Multiplayer online games

That's no longer the case. I'd say about now, there are more multiplayer games that you can play, as opposed to ones you can't play.

See: https://areweanticheatyet.com/ as reference, but it's not very up-to-date, so https://www.protondb.com/ would probably be a better reference.

Only listed the 'bigger' ones, but you have a rather full list here if you want to check your favorite games: arwianticheatyet.com

Nope, just works. There are some games that use invasive kernel-level anticheat that wont work as Linux sensibly blocks anything that shouldn't be messing with the kernel, but I'm not personally interested in those games anyway. EAC and Battleye both support Linux, but requires devs to tick a box, which there's several that can't be bothered.
