I've mentioned these before and I'll do it again:

• Exanima - Read about the features. This one is more impressive than the screenshots make it look (at least for me).
• Lunacid - I love the visual style and atmosphere of this. I also enjoyed Lost in Vivo by the same developer.
• Praey for the Gods - This one is for anyone who's looking for more games like Shadow of the Collossus.
• The Upturned - A cartoony horror-comedy game with a great sense of humor.
• Withering Rooms - The story is interesting and the atmosphere is great.
• Your Spider - This one is possibly my favorite indie horror game.

Shadow of the Forbidden Gods - a strategy game where you play as the ancient cthonic entity waking up because the stars are right. Set in a fantasy world where the forces of good slowly become aware of the coming apocalypse and attempt to forestall your return. You have to get past the janky UI and some dreadful AI art, but the gameplay is unique and satisfying.

Hmm, ones no one knows about...

Probably Icy: Frostbite Edition. Pretty solid, not something to get full-price necessarily but it was pretty good when I played it like 5 years ago. Interesting turn-based combat.

Also, OneShot. My avatar is from that game, I really think almost everyone should play it.

I'll add Noita to the list of hidden gems. And Baba Is You.

From The Depths -- very deep large vehicle design and combat game, prepare to happily lose months of your life

Barotrauma -- help crew a submarine under the command of the captain to perform missions in an alien open world. fun multiplayer with good in game VOIP

The Witcher 3 (/s)

I'm currently totally hooked on Tiny Rogues.

After Hades, I hope some folks went back and played Supergiant’s other titles. I love them all. But even amongst them, Pyre is the underdog, unknown, shunned. And I think it’s fantastic. The music and writing is top notch. You can really see the bones of Hades in all their games, but they polished their world building and story telling to perfection in this one.

OMG-Z It's a playstation mini for the PS3/PSP.

Warp on the PS3.

Donut County isn't really a nobody game. But I never see it mentioned.

Blasphemous.

Fantastic metroidvania meets soulslike game. The art style, the lore, the atmosphere, and by God - the music!

The combat is not super great, but it's capable enough for a metroidvania.

I haven't played the second one, I hear it's kinda hit and miss.

Universim.

Sebil Engineering has a really fun mechanic I've never seen before. Its like those Hot Wheels tracks you always wanted as a kid but your parents never got you, but even better. I guess its a traffic control game? Anyone have other examples of these?

Dominions (Dominions 6 just came out, but it's an iterative game so try 4 or 5 first)

So it's like civilization and battle simulator had a baby, where armies are managed by the unit and there are simulated battles of thousands.

But all the civs are loosely based on different existing mythologies and there's a crazy complex magic system

Oh, and you get to create a god that you can totally battle with.

If you like civ-like games, it's a really unique and satisfying twist on the genre with an incredible amount of sheer depth.

Paradigm

I'll toss 2 mobile games on the list. Desert Golf and Golf on Mars. No ads. No stupid paid trinket nonsense. Just a couple bucks for the game and a very chill and casual 2D golf game.

Null Gravity Labyrinth for everyone who likes labyrinths
