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].
If you're in the mood for an RPG that can be played in single-player as well as online then you might want to take a look at Shroud of the Avatar, as it has a free trial going once again.
Bounty Battle looks extremely fun, with a cast taken from other popular indie games and it's now been fully funded on Fig. They also announced some new character's coming.
Rusted Warfare is quite a fantastic little RTS game with clear inspiration from older RTS titles like Total Annihilation and it just got a huge update.
I'm going to be honest, I think Feral dropped the ball on this one quite badly. Total War: WARHAMMER just got a new DLC, 'Norsca', which released for Windows. Sadly Linux & Mac gamers have to wait on it which wasn't communicated very well.
Apps, apps everywhere! It seems Paradox are doing their own client now too. I have no idea how long it's been a thing, but it appears it will support Linux too.
Astral Traveler, what the developer is calling a 'runner style' racer, where you keep on going and going while dodging obstacles and shooting down enemies is releasing next month, with Linux support.
