Depends, if you want to play online, tough luck. Most anticheats refuse to work with Linux, the smaller games probably work fine, but if it's somewhat mainstream (fortnite, valorant, cod, rainbow six, etc) it probably won't work. ProtonDB has a great list.
That's because it's built off of source and uses valve assets. A clone in godot would be in the clear.
Problem is that it has to be built from the ground up, so it's lots more effort to make.
While I don't think flatpak shouldn't replace traditional packages, I still like it.
Flatpak apps just work most of the time, they work without issues and are often very up to date. The sandboxing does have benefits because no apps interfere with it, the problem is that it doesn't work super well with other apps, sometimes the theming is off, and it doesn't work well with other apps, installing apps takes much longer, and it isn't as easily started from the command line.
The series title has no particular significance to the story. "Azumanga" is a portmanteau of the author's name "Azuma" and "manga", while "Daioh" comes from the magazine in which it was originally published, Dengeki Daioh. In the anime, "daioh" is mentioned during the next episode previews, used in context with the meaning "great king".
It's the main way I recognise regular posters
