Can you recommend me something from my library?

I see you have a FPS shooter Alien rage. I've haven't finished it yet, but it wasn't a bad game (if you like nonsense spawn of enemies which can survive headshot and no way to heal yourself). But you have some really cool RPGs like Risen or Two worlds, these will definitely worth a shot.

I would recommend using https://servc.eu/rsg/ :) i rediscovered a few games I forgot I had by doing it

Overlord is a good game you haven't tried before. :)

Just Cause 2 is a lot of fun. Also the Princess Remedy games are cute and short.

It seems you didn't play Psychonauts past the tutorial level, despite having some played time.
So, you either disliked the game or didn't play it xD Either way, I find it really creative and entertaining

Edit: Oh you're already downloading it x_x
So, here's more:

Rogue Legacy. It's the type of game you'll die a lot but still feel you're making progress. It has a fun gimmick
And yeah, you should definetely buy Portal!

Let's see...looking through previous comments, I already see Psychonauts & Just Cause 2, so let's see what else I can find that I don't think has been mentioned yet...

The LEGO games aren't challenging by any means, but they're simple and light-hearted. I recommend them be played couch co-op if you can. Good way to spend time with siblings/SO, even if they're not very good at games.

Splasher seems like a decent platformer, though I've yet to play it myself.

The Marvellous Miss Take is a charming little stealth game. I see you have some time into already though. Not sure if you beat it already or put it down and didn't come back.

good luck with your endeavour! 😄

Why not join Play or Pay, you get a bunch of new picks each quarter and you only need to play 1 or 2 of them to fulfill the group requirements,
personally it has helped me sift through a lot of my backlog for treasures.

Card Hunter's really fun if you like table tops, I've sunk a couple of hundred hours into it.

which the most easy and fast way to have a look to someone's game library without having to add them as a friend?

Thank you in advance

If you like JRPG i think this one is interesting
https://store.steampowered.com/app/23310/The_Last_Remnant/
or... this one if you prefer the occidental way
https://store.steampowered.com/app/34010/Alpha_Protocol/

I have played The Last Remnant at the the time it was realesed on xBox 360... and i liked it a lot, unfortunelly i never played alpha Protocol but i have heard good thing about it

You have so many game's and you've barely touched any of them.

I've played a lot of games throughout my life and I can prolly help you find the perfect fir for you but you'd need to give me a very specific criteria.

If what your only criteria is that a game is straightforward not slow and starts immediately, go for either Devil May Cry 4/Reboot (if you're new to the series) or maybe Bayonetta.

Condemned: Criminal Origins for a good suspenseful horror action
Puzzle Agent 1 & 2 for relaxing humor and mystery atmosphere
Lord of the Rings Online if You want that MMORPG feel with a helpful community and high populated servers even today (best of all, it's free)

X-COM: UFO Defense (showing it's age by now, but still a lot of fun)
Both Princess Remedy games. (They're short, but entertaining)
Human Resource Machine (yay, programming puzzles)
Binary Domain. (somewhat standard third-person shooter, but I liked it)
Rogue Legacy

And maybe more Infinifactory

Phantom Pain

I see you have: Cubicle Quest, Sins of the Demon, Soul Gambler, and Stories: Path of Destinies.

Cubicle Quest is probably the best in my opinion life-sim satire. You have money problems and plenty of other life problems to deal with. You learn people-skills and other skills to deal with each type of bad guy.

Sins of the Demon is actually a short, but very well-done story-driven RPG with some interesting character backstories.

Soul Gambler can be beaten in about an hour or two. It's a choices-matter comic book strip type of game. I enjoyed going back and changing my decisions just to see the outcome. It's a bit cheesy, but the art is definitely charming.

Stories: Path of Destinies This one is a bit light on story, but it makes up for it with some pretty great branching choices-matter scenarios and a much simpler Batman Arkham-style combat system (which was really addicting). I couldn't wait to face off against hoards of baddies.

Path of Exile if you enjoy Diablo 2-esque games. You can play many hours without spending any money.
Fishing Planet. It's pay2win, but you can still progress and have fun. Progressing is faster with real money spent.

Quickly scrolled through games with 0 playtime, these are which caught my eye and you should try them.
Binary Domain
Borderlands
F.E.A.R.
Metro 2033

You have played a few hours of the second game but you have not played F.E.A.R. whitch is the best one!
