For me, it’s Factorio.
a game in which you build and maintain factories.
It even has Wayland support!

Graphics
- Added support for Wayland on Linux. To enable it, set SDL_VIDEODRIVER=wayland in your environment. (thanks to raiguard)
What’s yours?
EDIT: Great Linux ports* not like some forced ports that barely work or don’t.
Rimworld for me.
(I have never tried Dwarf Fortress.)
Honorable mention goes to War Thunder, while it isn’t on of my favorites, I was still a bit blown away to find out it runs natively on Linux.
