Here's a little under 10€ historical lows biased AF recommendations list:

Death and Taxes 70% (3,59€ for me) and 85.33% positive rattings

• This one is really funny. It just is. The art is great as well. Trust me. Get it. DO IT.

The Forest 75% (4,19€ for me) and 94.24% positive rattings

• You can't go wrong with The Forest if you like stuff like Subnautica for example. Plus it's got multiplayer. You don't have to die alone!

Catherine Classic 75% (4,99€ for me) and 85.32% positive rattings

• Really a classic tbh. IIRC this ATLUS game came out 2 or 3 years after P4 and the story + gameplay is as gripping as their SMT Persona games series + same art style. Although it's a little more mature it's not distasteful.
• Bonus points, it's pride month and there's a properly written minor trans character who's personality isn't built around their gender or comes off as overly preachy. Happens once in a blue moon people!(Try to give me crap this and I will shove my T vials down your throat. Fair. Warning.)
• I regret not getting the SE of this game when it came out, it was really funny. It included the main character's boxers and T-shirt.

Viscera Cleanup Detail 55% (5,84€ for me) and 90.81% positive rattings

• This is honestly the BEST game to play with someone if you just want to chat while playing and cooperating. It's good for making friends or catching up with friends. Doesn't really take a lot of brain juice to play so you don't have to focus on two things at once. It's just chilling and mopping up "gruesome" death and destruction scenes. It has single player too so don't sulk just yet. I'm a bit of a clean freak IRL so this one is just terapheutic for me sometimes. You'll recognise some of the stages from other games by the way.

In Sound Mind 70% (8,99€ for me) and 89.59% positive rattings

• I'm currently streaming this on Twitch and I am honestly having a blast. A horror game that deals with a range of mental illnesses while emcompassing supernatural elements + other things that I will not spoil for you. The soundtrack is by The Living Tombstone and it's also absolutely amazing. Plus, you can pet the cat! That's a MUST in ANY game.

Road 96 50% (9,98€ for me) and 88.93% positive rattings

• This one is another really great game with a great story and OST. The replayability is a little... Meh. But at this price I think it's definitely worth it. You're better off going in blind on this one so no spoilers.

Devil May Cry 5 67% (9,89€€ for me) and 93.29% positive rattings

• The DMC series is one of THOSE series for me like MGS (DmC doesn't count, DmC doesn't exist, get off my lawn) so I was honestly pleasantly surprised with DMC 5. We get our boys back the way they're supposed to be with the dynamic that they always had, our BAMF ladies are back with an addition to the cast, everything is edgy, over the top as hell, funny and Dante is finally becoming the cringe uncle we always knew he would be. Vergil is still Vergil. Nero isn't as whiny... AS whiny. Basically all is right with the world... Erm... As right as the world can be in the DMC universe at least.
• Bonus points, go watch some of the CH players queue up combos on YouTube and tell me that that is not the MOST satisfying thing to see. Beautiful.
• My most biased AF entry TBH. These game series are my babies.

So far I have refunded 2 of my purchases, Assetto Corsa and Geometry Dash and only one is pending.

Any recommendations for someone who likes rogue-lites and metroidvanias with 3700 games and a $10 budget? Not into card games

I've been noticing that a number of games on my wishlist, are actually on sale for cheaper on sites like Fanatical and Gamebillet. So maybe it would be a good idea to double check those sites before making a purchase on Steam.

Gamebillet seems like it has better discounts on a number of AAA games. (For example, Horizon Zero Dawn is 65% off on Gamebillet vs 50% off on Steam)

90% discounts:
The Treehouse Man
RIDE
Ride 2
Down in Bermuda
Summer Catchers

Here is a list of 90-100, 50%+ discounted games, all on new or repeated historical lows played before and they are worth to play if meets the genre choices of the players:

what to do with one card when 9 cards are missing :)

i picked up for - 75%:

• heroes of might and magic 3 HD (afaik returning low)
• Hand of fate 2

Is anyone having serious issues with cards? I don't get any card after the discovery queue since yesterday, the ones I got until now are in my inventory even after I made a listing for them, didn't show up in the confirmation section on Steam mobile and there's nothing in the market. When I try to sell it again I get the message "there's already a listing bla bla bla", but there isn't.
