The Westport Independent is a censorship simulator, in which you play as the editor of a newspaper, choosing which stories to run and how to edit them in order to avoid angering both the authoritarian government and political radicals who want to take them down, while also appeasing your journalists, who may get angry and quit if you censor their stories too much.

A bunch of my favorites have already been listed, so I'll just mention the one that wasn't: Antichamber, a first person puzzle game that's probably somewhat like Portal in terms of how it requires you to rethink your assumptions about how space works, but it's a very different game, both mechanically and in tone. I don't want to give away too much, but it's a mix of weirdly unsettling elements (although it is by no means a horror game), a design that's actively trolling you in ways that will make you laugh, and mechanics revelations that will have you scream "Wait, I could have done that this whole time?!" It's one of those games that I wish I could delete from my memory and play for the first time again.

Really engaging game with a short, easy to understand mechanic. It's fun just to put on and fly around for a bit every now and then.

Some games I recommend:

Alina of the Arena: A roguelike deckbuilder game. It has turn based tactical battles. There are lots of cards and builds you can try, but there is a fair amount of randomness to it. So you have to go with what you get.

Unreal Life: A really strange, surreal adventure game with a talking traffic light. Great visuals and music.

YumeCore: Just a short little game where you beat up people in a hospital. Why? Why not?

Flood of Light: Great little game with pretty much one core mechanic (direct lights). The Engliah translation isn't the best, but I really liked the atmosphere.

Brotato: Is it a hidden gem? I don't really know, but it is a fun "Vampire Survivor"-like game and a huge time sink. Great shop mechanic and large amount of characters and items.

I would recommend Wintermoor Tactics Club, its a top down turn based tactics game with a cute and wholesome story. I also found it quite funny

Ooh, I love finding obscure indies. There are an awful lot of games on Steam and Itch and other platforms that are amazing experiences, but that almost no one has ever played or even heard of for one reason or another.

One of my recent favourite zero-budget indies is Sally Can't Sleep, a strange first person platformer with a lot of focus on fun, versatile, and exploitable movement mechanics. The dev sacrificed visual polish for quantity and style, so the game has a lot of interconnected levels with a big variety of different mechanics and visual styles - it's a really good example of how much a solo developer can accomplish.

Another one is Worlds, which is a 3D stealth-shooter-platformer-adventure? I like it for the same reason as Sally Can't Sleep, it's ambitious and creative, and you can really feel the developer pushing against their limitations to release something that punches far above its own weight.

Also, both these games are very cheap, even at full price!

Pyre by Supergiant - You have likely heard of Hades by this studio, but Pyre is a whole different beast. It's basically fantasy basketball set in the underworld, with a variety of magical species with different abilities in the game. It also has (as is this studio's habit) absolutely stellar writing, music, and 3 dimensional characters.

Don't sure if it's exactly hidden but for me Dungeons III (and 2) has been unexpectedly fun. It takes everything that made Dungeon Keeper and it takes a level higher. Pretty fun game.

If you liked Hades, play Ember Knights. It’s in early access but I legit put 6 hours in my first session cuz it scratched that Hades itch juuuuuust right

recently got completely addicted to a text-based Indie RPG called Roadwarden. The story and characters are incredibly rich and the gameplay is full of satisfying little moments of "oh, I have just the item for this!" or "another character told me this tavern keep doesn't appreciate jokes; I better get straight to business". I haven't beaten it yet, but I can't wait to see where it leads!

If you like space, you should play Homeworld and its sequels. Incredible game.

If you like chill strategy, try Terra Nil, Islanders, and Terrascape -- they're all really fun and Terrascape has turn-based multiplayer!

If you like puzzle games like Myst, Cyan has Obduction and the slightly controversial Firmament, which I thought was a lot of fun. Quern - Undying Thoughts is in the same vein and feels a lot like Myst or Riven.

If you like Halo's multiplayer with an added Portal gun, try Splitgate. The developer isn't going to be adding more content as they are shifting focus to a new game, but it's still really fun.

If you like boomer shooters, try Amid Evil it feels like Quake, Unreal, and Hexen/Heretic. It'll get your heart racing for sure.

Super Auto Pets has replaced Hearthstone for me, it's fantastic.

I'd personally recommend Rain World, although it has a reputation for being hard, and you'll probably die a lot so this game has to be approached with patience

Hyper Light Drifter is a really pretty game with tight controls, fair difficulty, excellent music, and some of the best atmosphere of any game I've played.

Ctrl Alt Ego

It's like a System Shock or Prey 2017 that has even less emphasis on "conventional" combat and more general problem solving. In some ways I feel like it's what you get if you grow an "immersive sim" out of a "puzzle" game like Portal instead of out an FPS or RPG.
