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.

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!

Super Blood Hockey. 80% off, about $3 USD.

It's a very well made pixel art game where you play hockey and you can beat up the other team. There's a franchise mode as well, so you'll want to balance how much fighting you do so your players don't get too hurt. There's local co-op so you can play against friends (or use steam remote play together).

PlateUp!. 40% off, about $11 USD.

Similar to Overcooked but you need to manage your restaurant and make sure you don't fail a single order. It's a rouge-lite, and you can move everything around in your restaurant and you kind of manage the menu as the days go on, but you get a choice whether to add option A or B, so it slowly gets more complicated. Very fun with friends, steam remote play together works here as well.

Bone's Cafe. 30% off, about $11 USD.

Similar to Overcooked and PlateUp!, but I feel like it's more geared towards single player (but there's local co-op as well). You have to manage your restaurant and menu (can make it as easy or complex as you'd like), while also maybe killing customers to harvest them for ingredients :) You can spawn in helpers and you can show them a repetitive task to do and they will do it.

Wytchwood is a fun crafting adventure game with a lot of fetching. Not too long of a game either and I finished it in a few days.

I've already got a Steam Deck and I really enjoy it, but I've been eyeing the Dock for a while too. It's on sale now for even less than the alternative I was considering so I'm probably going to grab one very soon

I'm always pretty keen on little indie city management games, this Roman city building game I've seen is pretty good, reminds me of old Caesars 3
