Steam, I can install the Steam client without any problems on moat distros, also Valve has done a lot of things to make the Linux gaming better.

Gog doesn’t have a desktop app for Linux, they’re focused totally Windows so I don’t care about it.

If I want “DRM free” games, then I pay for the original version with DRM and then pirate it to play whenever I want.

Try using japanese subtitles in animes you have already seen, it helps a lot honestly.

I can’t stand dubs, I think that japanese VA are a lot better. Anyway, I have been reading subs since I was 8 years old so I read them so fast that it doesn’t bother me.

Garuda was my first distro too, after it I switched to Endeavouros, I think that endeavouros or arch fill those requirements.
