If you like your weird games with no speech, check out One Eyed Kutkh which has been released for free on Steam. It's based on the fairy tales of the Far North, apparently.
Feral Fury is a twin-stick shooter with an overall dark feel to it. I've played it for a while and I've grown to really enjoy it, even if it's a little punishing.
Croteam have recently released both Serious Sam VR: The First Encounter & Serious Sam VR: The Second Encounter on Steam. They both use their new Fusion engine which comes with Linux support, Vulkan and 64bit.
The Road Redemption developers have now updated the Linux build of their combat racer and I've spent a little time testing it. It actually works pretty nicely now!

Transport Fever has just gained a big usability patch that promises improved performance, better RAM use and more. The problem is that the Linux performance is still terrible.
While I usually don't like pre-orders, Paradox is certainly a developer worthy of it. Since we know this will have no problems with Linux support. Stellaris: Utopia is a massive expansion too, I can't wait!
Valve have done another push towards video content with Steam now partnering with Crunchyroll to offer certain series of Anime for purchase. They also have a bunch of Anime classed games on sale.
