https://store.steampowered.com/app/935930/Reignfall/ - 90% off, extremely cheap (0,39 EUR here) strategy game with nice reviews (88%). This dev also has a retro horror shooter with 98% positive reviews which isn't steeply discounted yet. It seems they are good at producing fun low budget games.

https://store.steampowered.com/app/550990/Viktor_a_Steampunk_Adventure/ - 90% off, new historical low, was added to the Summer Sale today. Comedy point & click game with Austria-Hungary as setting.

https://store.steampowered.com/app/809140/Cliff_Empire/ - 35% off. Not a steep discount but I wanted to mention it as after a long time without dev activity this year the game received several updates and a graphics remaster.

https://store.steampowered.com/app/1497640/Traitors_in_Salem/ - 2,49 EUR alone and 1,87 EUR if you own Town of Salem and The Coven DLC. It is really underrated game similar to Among Us. This is historical low to boost playerbase.

Middle-Earth Shadow Bundle - 85% USD$10.49
Shadow of War Definitive and Shadow of Mordor GOTY.
There is stuff that is "retired" in both games, so keep that in mind if you are looking for leaderboards and PVP stuff. You cannot move your character (Nemesis) from one to the other either, but these are two pretty huge AAA games in the LOTR-ish universe and their DLC/Expansion for pretty cheap.

Does anybody have problem with "disconnecting of STEAM account", when paying with card? 🤷‍♂️

anyone else can't checkout the Indiegala Collection bundle?

just bought Space Hulk Deathwing Enhanced Edition at 83% off if you own Necromunda

Here's two more games I've found... for those who like weird stuff.

Stikir -90%
The Grim Ending -90%

This is my last chance to find a few games for a bit, I have around 10-12 dollars and I enjoy pixel graphics/rogue-lite/Metroidvania and action rpgs. The only issue is I have about 3700 games so finding something I haven't tried or played is difficult. Appreciate any helpful suggestions. I have played many so unless it's a hidden gem or underrated there's a strong possibility I have tried it before.

A another -90%, just bundled one time in 2014, Turbo Dismount

Just wanna put a small recommendation down for A Year Of Rain (90% off)
https://store.steampowered.com/app/319540/A_Year_Of_Rain/

Now to explain why. The game plays JUST like Warcraft 3 (old school race-specific RTS game). And because of that it's a lot of fun. The downsides that people complain about are the following though, 1) the pathfinding is a bit shit (so it's generally better to manage where the units walk), and 2) the AI ally is generally shit. The Ally point is a big one because the whole campaign is co-op friendly, so you NEED the ally to help in most cases, though there is a really nice solution, play the campaign co-op with a friend :).

are the sale cards still dropping ? if yes till when ? (till the cards disappear from inventory ?)
