The team behind ATOM RPG seem to have done very well, not only have they made a pretty good Fallout-like RPG that's seen great post-release support, they're also teasing something new.
Orangepixel have announced that Gunslugs:Rogue Tactics, their action platformer with stealth elements is closing in on a release date and it's looking great.
A recent discovery after randomly going through my Steam Discovery Queue is What Never Was, a short and free story-driven adventure game from Acke Hallgren.
Like the previous releases from Egosoft, it started a little rocky but to their credit they're really pushing hard on getting X4: Foundations into a good state.
There's a lot of good new games coming out but sometimes it's good to remember some older gems, recently I've started playing Polychromatic again and it's such a fantastic arcade twin-stick shooter.
