Gaming

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.

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

Superflight

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.

I think 5D Chess With Multiverse Time Travel fits the criteria, and it's completely insane to boot

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.

Ring Runner: Flight of the Sages is a 2D top-down space shooter with RPG text-adventure elements outside of the combat scenarios. I found it a super fun game with an insane amount of content. Probably over a hundred hours worth. There's a bunch of weapon and defense customization when it comes to combat, and there's probably thousands of varieties of ship you can build for whatever duty you need it to do.d

I believe if you play with a controller it has twin-stick controls, but on PC the controls are more like Elite: Dangerous or No Man's Sky, just in a 2D environment.

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 can't really recommend this because its more or less a dead multiplayer beta that's not even legitimately available anymore but Shattered Horizons was a microgravity first person shooter that was really cool. So, uh, if there are any indie devs in this chat, uh, please steal this dead idea!

If you like surrealist art I highly recommend Hylics and its sequel

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!

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.

One of my favorites over the past few years is Prey(2017) it was made under Bethesda so I wouldn’t say it’s underground, but It didn’t get the popularity and fan base it deserves. Essentially a open world (as open as a world can be in a giant space ship) that allows you to explore and fight creepy creatures. It also gives you multiple ways to solve the problems you face as well as Multiple endings and story branches to choose from. I played for 33 hours and it was so worth the price it was on sale, (wish I could remember) but it would also be worth $60 as well. It reminds me of a high polished Skyrim at certain points. Would highly recommend

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!

Firewatch - recommend you wait for a sale but its a great story game that is on steam and gog and even native Linux

tabletop simulator - tons of card and board games that you can play with your friends if it exists it might be ported has native Linux

golf with your friends - great mini golf game to play with your friends similar to tower unite golf but better has native port

american/europe truck simulator - trucking game that real truckers say is the most realistic trucking game and they try to help with all issues and is even native Linux

https://store.steampowered.com/app/1641020/my_brother_lives_in_a_canyon - my brother lives in a canyon - great story game that is made by one person and it does not take long

Bloons tower defence 6 - tower defence game where you pop the bloons to defend your base

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.

I’ll say CrossCode. 2D hack-and-slash set in a futuristic MMO. Way too good, way too unknown for the genre that it is.

It's admittedly gotten a lot of shout outs with Diablo's release, but Grim Dawn. Just a super great old school ARPG with a fun multi class system. I think I made a mistake by letting it be one of the first in the genre I really got into, so it's kinda tough to find another one that competes.

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

Narita Boy is a really cool glitch aesthetic sidescroller

I enjoyed atomicrops tremendously
