Hidden gems of Steam Summer Sale 2017 (July 5th last update - thx a lot to all for discoveries)

Thank you for the great thread! I bought Detective Grimoire, I LOVED the original free online version of the game.

Thank you for your thread Coleypollockfilet! ^^

This one appeared on my radar during the sale because it looks good and it has a lot of potential. It's still early access for a reasonable price.

(Do not hesitate to post other gems you want to make discover, even if the list is not updated)

The Metronomicon (rhythm RPG)
50% off, $9.99 or regional equivalent

Short description: Suggested because Before the Echo is in the list, and this one IMO is far superior.

I highly recommend the game WUPPO, it's a weird medtroidvania/shoot-em-up/adventure/rpg mash-up with a huge world. Seen a friend play this, will start my own playthrough soon.
Plus the rating was 100% until some douche recently made the first negative review for being the first to make a negative review.

I recommend Rad Rodgers: World One ( 8,99€ (-25%).). An excellent platformer and an excellent tribute to Commander Keen.

Added personnally at start of the thread :
Amphora (Near historical low never bundled - play an amphora spirit in a bright scenery)
Ironcast (Near historical low bundled 1 - a steampunk match3 rogue-like with mechas)
Buzz Aldrin Space Program Manager (not historical low but never bundled - play U.S. or USSR and reach the moon before the yankees/red in this spatial program management)

Added personnally now :
Passpartout starving artist (out of sale but new game from June 2017) paint.net based game short but high replayability
Predynastic Egypt (historical low never bundled - indie gem about ancient egypt casual strategy)
Book of demons (near historical low never bundled - high quality indie tribute to Diablo)
Snake pass (historical low never bundled - A platformer where you play a snake that wriggle... in 3D yes)
TurnOn (historical low bundled 1 - play an electricity ball in out-of-power city)
NBA playgrounds (near historical low never bundled - NBA Jam fast 2 players basketball inspired game !)
Diluvion (near historical low never bundled - Jules Verne style submarine exploration)

Airscape - The Fall of Gravity

I have posted it in games under a dollar thread, but it deserves to be here as well. It sold really bad, TotalBiscuit even made a video about it.

I'd like to point out the Crystal Shard Adventure Bundle - http://store.steampowered.com/app/551840/

It's a collection of three small point'n'click adventure titles from the creators of Heroine's Quest, which is a highly recommendable free-to-play mix between an RPG and a point'n'click adventure title. I enjoyed it very much, so I bought this collection to honor the devs (and also because it looks amazing; if you like the Blackwell style, you'll dig those).
The Crystal Shard Adventure bundle is at its all time historical low at 30% off for 4,19€

One i don't add to the list because bundled 3 times already but it's good to know it exists :
Out There Omega 66%off 3.39€

It's the game that inspired no man's sky (some would think NMS copied) in 2D, in faster, (in much better... yeah this one is subjective).

Common points :

• Same start : repear exactly the same item with iron
• Same inventory system
• Same switch ships system
• Same possibility to learn ET words from artefacts
  ... and i probably forget many, they are so similar.

However i can add this one to the list XD
Space food truck
30%off 6.99€ (but the base price just went down this month from 20 to 10€) near historical lowest, never bundled
It's another game when you jump from planet to planet but with cards and highly random !

thanks for this list I added 13 games to my wishlist now I have to decide what to buy ._.

you SHOULD add Psychonaults to this list, although is not actually a hidden gem, this game is way underrated, and is so cheap for its value!

tbh it's not even near the HL, but I've heard geat stuff about Hot Tin Roof
http://store.steampowered.com/app/253390/Hot_Tin_Roof_The_Cat_That_Wore_A_Fedora/

Also, with the new layout, the RaChart enhance rworks xD

Gah, why did I open this page!!! A good number added to wishlist but I think I may have to break down and buy Shrouded in Sanity

Super Panda Adventures is a short and sweet little Metroidvania, I think it's pretty great for the price: http://store.steampowered.com/app/311190/Super_Panda_Adventures/

$0.74 at 75% off

You should include the Trails in the Sky trilogy, Xanadu Next and all Ys games. Hell, anything Falcom related is a gem if you like JRPGs.

The Trails games have a really deep and fantastic story, backed by a superb world-building and great soundtrack and turn-based combat. Every NPC has its own name, personality and story that unfolds during the game (all dialogue changes after almost every story event), they are affected by the world and you. The first game is quite slow, but when it picks up, you're in for a treat. Also, if you decide to pick up the first game, you will want to play the second one immediately after finishing it, trust me.

Xanadu Next is like Diablo meets Zelda. It focuses more on exploration and combat, and most of the story is left for you to discover.

The Ys games are fast-paced action RPGs. Each one of them is pretty self-contained (with the exception of Ys I+II and Origin), so you can jump in at any game. Also, being a Falcom game, of course the soundtrack is amazing.

Umihara Kawase series is -70% off right now, 8.99$/8.39€ for the entire package. Cult classic platformer that deserves more recognition.

Ubermosh games are some of the best fast-pased games imo. They make you feel badass even if you don't even know what the hell it's happening :P
