I am the owner of GamingOnLinux. After discovering Linux back in the days of Mandrake in 2003, I constantly checked on the progress of Linux until Ubuntu appeared on the scene and it helped me to really love it. You can reach me easily by emailing GamingOnLinux directly. You can follow me personally on Mastodon[External Link].
For those in need of a good-looking action-RPG that offers tons of loot, Last Epoch certainly seems interesting. There's also now a Linux demo available.
The Swords of Ditto is the new compact action-RPG from developer onebitbeyond and publisher Devolver Digital and it just released, although it has a big flaw right now on Linux.
Doom, the classic first-person shooter has a huge modding community and it's incredible to see what people make. The latest I came across is a nonviolent mod named Mr. Friendly.
Remember Apocryph? The brutal FPS inspired by the likes of Hexen, Heretic, Painkiller and so on. Well the developer has announced that they're aiming for an April 27th release.
