If you don’t mind challenges, FromSoftware titles are pretty decent, Elden Ring is a big as time sink, my first playthrough was about 120h.
Skyrim with a buncha mods is always a thing, you can get many replays out of that.
If you like story driven games you can always go for RPGs. I like JRPGs the most, the final fantasy series is pretty good, final fantasy 9 is my favourite.
I’m on a full AMD build (updated the post with the info).
I’m currently on win10, I will switch to linux during xmas holidays when I have some free time.
Also I have only surface knowledge about wayland and x11, I know that they are window system protocols and that wayland is more modern, can you switch between them like how you do with desktop environments? And it’s worth going for a specific distro to make things easier like garuda or nobara if you are mostly focused on gaming?
I updated the post with the PC specs, but it’s pretty much a full AMD system (new build since my old i5 6600K and gtx1070, was about time).
Why isn’t wayland recommended for gaming? I just bought myself 2 screens, both of different resolutions and framerates, and as far as I’m aware x11 will set both to the same one because it doesn’t support different ones.
