Gaming

For me it’s Songs of Conquest - spiritual successor of Heroes of Might and Magic 3. It looks great, the gameplay is awesome, they took all of the best parts of HoMM and got rid of the more frustrating ones (for example there is a unit cap for a single slot, so you can’t have 2000 skeletons in a single unit). There are also some cool new mechanics, like every unit gives some kind of essence, which is used as a resource for using spells, so depending on your team composition you get access to different spells. Overall definitely worth checking out for every HoMM fan!

Here are a few that I really enjoy (though their level of "unknown-ness" is debatable):

Mini Metro: https://store.steampowered.com/app/1127500/?snr=1_5_9__205

Demeo: https://store.steampowered.com/app/1484280/?snr=1_5_9__205

Evoland: https://store.steampowered.com/app/1020470/?snr=1_5_9__205

Most of these aren't really 'hidden' but there are some good deals on some of my favorites right now:
Skyrim - $10, which gives you access to:
Enderal - Free but requires Skyrim in library
Witcher III + DLCs - $15
Raft - $13.39
Grounded - $24
Satisfactory - $16.49
Subnautica & Subnautica Below Zero - $18
Valheim - $12
Age of Empires - $5
Halo: Master Chief Collection (7 Halo games) - $10

If you're a fan of co-op survival and adventure games, Grounded is great. There's also Raft which is a more chill style adventure game.

Personally I'm probably picking up in this sale:

• System Shock
• Outer Wilds
• Aquatico
• Pummel Party
• The Long Dark: Survival Edition
• A Way Out
• Phasmophobia
• Halo: The Master Chief Collection
• Voidtrain

i'm sure you all have heard of Outer Wilds (which i highly recommend and is 40% off right now) but a lesser-known game is Rain World. it's an absolutely brutal survival platformer where you play as a little slugcat trying to find their way home in a dying world. it's not for everyone, but if you like exploration, ancient mysteries, action, a bleak atmosphere, and you don't mind dying a hundred times, absolutely give it a go

thought of another: Eastward.

this is a flawed game, make no mistake. the pacing is, at times, abysmal. but man if it didn't punch me in the gut by the end of it.

also I dunno if everhood is on sale but that game is also strange and fun but flawed. perfect games to get on sale imo

just grabbed god of war, disco elysium, and hellblade senuas sacrifice...

as far as recommendations go, Mass Effect legendary edition and dragon age are very enjoyable if you like RPG with a focus on lore, story and characters. Red Dead Redemption 2 is a wonder and a steal at $20. Witcher 3 for $12. Horizon Zero Dawn for $16.50

I suppose it depends on what a person considers a hidden gem because everyone's tastes are different. I'll list a few categories and at least 1-2 of my favorites in those categories that I've found on Steam and are currently on sale:

Exploration/Base-Building:

• Grounded
• Raft
• Rimworld
• Subnautica/Subnautica: Below Zero

Story based/Farming/Romance:

• My Time at Portia*
• My Time at Sandrock

Visual Novels:

• Basically anything made by PixelFade (Ace Academy, Ethereal Enigma, Crystalline). One of the few English-based VNs that are fully voiced in English and have a pretty decent plot/story. Interactive with different choices affecting different outcomes and even some minigames at least in EE.
• _Nekop_er Hush Hush. Ok, listen. I'll admit there IS an 18+ DLC for this but it's not necessary to enjoy the game. It honestly has a pretty interesting story/premise and I did get pretty heavily emotionally invested in the characters.

*Note that MTAP has been fraught with issues. Although these issues don't necessarily make the game unplayable, and it's still enjoyable, be aware that it is was Pathea's (the studio) first such attempt and as such they were still learning. Their second game Sandrock has solved a lot of the issues and it's not necessary to play the first one

A few to add in:

Solasta: Crown of the Magister - Old school D&D and tactics RPG. It’s indie so has rough edges here and there, but it’s so fun, and there aren’t a ton of games that fill the void.

Dungeon of the Endless - It’s a tower defense / tactical game with great pixel art and one of the best soundtracks I’ve ever heard.

Battle Chasers: Nightwar - Excellent RPG that will remind you of old school Final Fantasy.

Tower of Time - Excellent tactical RPG

Detroit: Become Human - Cinematic narrative game about androids becoming self aware.

The Dark Anthology: Man of Medan - Cinematic narrative horror game, the first in a series of several, therefore if you enjoy there’s a lot more where that came from. (Made by the same studio that created Until Dawn.)

I'll just go through my library and pick out the ones that I don't think are very well-known or might have been missed by anyone who got into gaming more recently.

Demon Truck is a devilishly arcadey game, and at 90% off it is fifty cents so you are legally required to buy it right now. Once you play it for a few minutes, you'll want the BANGER soundtrack too, which was done by Zircon, costs $3, and is worth every penny. Here's a sample on YouTube if Bandcamp doesn't work for you. Game is a 40 megabyte download. What are you waiting for?

Approaching Infinity - What if No Man's Sky was a turn-based roguelike with retro tile-based sprite graphics? If that appeals to you, give it a look. The developer also has a more fantasy-oriented game called The Curse of Yendor.

Devil Daggers is worth trying if you enjoy fiendishly hard FPS games with pixel graphics.

Bots Are Stupid - it's a tight platformer where you control the character by writing a script to control its actions down to the individual frame if necessary. It has a level creator as well. If you've ever seen tool-assisted speedruns (TAS), this game is basically creating a TAS for something like Super Meat Boy.

If you have PCVR, give Ancient Dungeon a look. It's early access, but it already has that particular spark that tends to (and did) hook me, and it does a number of things phenomenally well, such as knife-throwing. In lists of top VR games, however, I rarely see it get a mention.

Distance is a racing game with where your car can jump, do flips, fly, stick to walls or the ceiling, and potentially get cut in half by the road hazards. It's by the same developers and is the successor to the equally fun and completely free Nitronic Rush.

It's not on sale, but at $5, Noitu Love 2: Devolution doesn't need a sale to be well-worth the price.

Lastly, Timespinner is a pixel-art metroidvania with time travel. I thought it was pretty fun.

I highly recommend CrossCode, currently only costs $6 (It also has a free demo if you want to try it first). It’s a really well polished game with a great story, and the action is amazing too. It also includes difficulty settings you can change if you feel yourself getting too frustrated (as I did sometimes). This video also sums it up pretty well. Hope you enjoy!

Death's Door 19.5€ → 7.8€ It's a very cozy game but still fun mechanics and adventurous. Kinda similar to Hyperpixel in feels. Spent 3 days while sick playing from the sofa, enjoyed every bit.

EXAPUNK - 50% - 96% Positive

If you like old time puzzle games, and have a pinch for programming, then you will love this. In this game you control bots by creating algorithms to extract data and other challenges. The cool part is you must study the game language and learn the lore from manuals and magazines that the game provides.

SHENZHEN I/O - 50% - 93% Positive

From the same creator of EXAPUNK, only the thematic here is electronics.

Road 96 - 50% 91% Positive

Summer 1996, Today is the day! You hit the road. Adventure. Freedom. Escape. Run. Flee the Regime. Try to survive.

On this risky road trip to the border, you’ll meet incredible characters, and discover their intertwined stories and secrets in an ever-evolving adventure. But every mile opens up a choice to make. Your decisions will change your adventure, change the people you meet, maybe even change the world.

Slipways. Very well made space puzzle game. This game really surprised me.

Also, hidden gems thread... feels just like home :)

I just got and am obsessed with UnderMine, an adorable roguelite dungeon crawler a la Binding of Isaac. Currently on sale for $5!

Timespinner: A really solid Metroidvania - very similar to older Castlevania games. It's on sale for just under $6 USD. Great deal. I got a solid 28 hours out of the game and loved it (tho, if you race to the end it isn't super long but still good for the price). Don't sleep on it for that price if you like the genre, and are itching for that old school Castlevania feel. An actual hidden gem IMO.

Broforce: Not a hidden gem, but a hilariously fun side scrolling shooter like Contra that you could play with a few friends (and levels going up and down, not just running to the right, plus destructible environments that you can use to kill your friends for laughs). $3 USD, hard to pass up even if you only play it for one drunken night with your friends. We all had a lot of fun with this. Maybe too much fun.

Toukiden 2: This game has been sitting at full price for years. I could never understand why. It's a Monster Hunter style game with a full open world for single player, but multiplayer gameplay for boss battles similar to MH. I had fun with it for a bit but I have been waiting for it to go on sale so I can play it with some friends. Significant sale at $23.99 USD compared to the usual $60 USD and it doesn't happen often. It's worth looking at. I enjoyed the few hours I played a lot, but I couldn't tell you how good it is overall. Reviews seem good.

Grim Dawn: Others have already mentioned this one. It's the successor to Titans Quest, and perhaps the spiritual successor to Diablo 2. Supports mods, which is great! Stash enhancements, character editors, etc. It's an ARPG game similar to Path of Exile and Diablo. Story is decent, there's some cool mechanics and choices matter type stuff, but even with those you can still play with your friends. You can get the game with expansions (totally worth getting) for around $21-$25 USD. Great deal and you'll be supporting a great company, Crate Entertainment takes care of their fans and keep supporting the game.
