I would appreciate your help to choose a game for my steam library!

Going by how much fun the previous incarnations were, Shadow Warrior 2 or Dishonored 2.
Shadow Warrior because it was action packed, had a decent enough story, great variety in levels and it felt fair.
Dishonored because it had lots of freedom in gameplay, seen clips of some highly skilled people doing crazy stunts, also had a decent enough story.

Hopefully the sequels will live up to their predecessors. :)

I don't think that any pre-sale game will ever get a discount, there's no need for them to do so. Also voting for games that aren't released yet is kinda pointless because I have no way to assess if they're good or not.
In my opinion you can't go wrong with any of the games Telltale has published, so +1 for Batman if you're into nice storytelling and I haven't played much of it but so far I like what Shadow Warrior 2 had to offer, a nice and simple "kill and blow up everything you see"-experience. :s
If you wanna go easy on your wallet you could also get Virginia, even if I haven't played it yet it looks like a nice story and kinda reminds me of Twin Peaks in a way (but I could be wrong about that :P).
But that doesn't mean the others you mentioned are bad, for a fact I got them all on my WL ;D, but these are the ones that interest me the most atm.

I am disappointed by the lack or should I say absence of cool small indie games on that list. Anyway I'd say go with Shadow Warrior 2. It's going to have proceduraly generated levels and weapons and it's most likely going to be super-awesome with a lot of replayability value. It might not have a very interesting story though, but Shadow Warrior games aren't known for their story and you have it on your wishlist anyway so I'll assume you don't mind that.

South Park - gameplay would be mediocre but it will have "southpark humor" :)
Good story + good graphics + good gameplay? I suppose that Dishonored 2 should have those tributes :)

I tried Far Cry Primal on PS4. It's really a nice game, the gameplay is not so different from the others Far Cry, but it's really refreshing to play during prehistory. It was a very easy game at the beggining, but they've added a Survivor mode quite challenging.

I didn't try anything else, but if I could, I would buy South Park The Fractured But Whole. I loved the first one, and would have played it again and again if my backlog was not so huge. If you like the serie, then you will love the game.

personally i want to pick CIV VI, but from the game you play a lot, i think Dishonored 2 Deus Ex: Mankind Divided Shadow Warrior 2 will do

dishonored 2 I have played the first one and i liked it very much ( maybe you would like to wait a bit until you buy it) the 2nd should be better DX.
Also the theme songs are awesome

Shadow Warrior 2 and Dishonored 2

I was going to buy FC Primal but in the end decided not to as it just seemed to be more of the same but with spears and axes instead of guns. I bought and finished Mankind Divided and enjoyed it, its cheap on cdkeys. I bought The Devils Daughter and after finishing the first case im kinda torn, you dont really get any kind of resolution, cant say to much without spoiling it, the game just moves on to the next case, again this is cheap on cdkeys. Cant speak for others i havent played or the games that havent been released yet. As i footnote im looking forward to the release of Mafia III, wont be pre-ordering, not after NMS, so ill wait and see how its recieved before i decide to buy or not. Good luck choosing and i hope you enjoy whatever you finally decide upon.

I'd say Shadow Warrior 2 and maybe Dishonored 2. I chose this two because they're the only ones that I'd play in your wishlist :/

civ 6 or south park

I vote for Sherlock Holmes and Dishonored 2.
I vote for Sherlock because, although there are other detective games out there, it is a genre that hasnt been done to death. Its story rich and choices matter, which means it will probably be a meaningful gaming experience.
I vote for Dishonored 2 because the first one was so brilliant to me. There was story, but the strategic options for gameplay with so many secrets is just what I like.
Good luck in choosing.

King's Quest - Season Pass probably. Or Syberia 3 since I loved the earlier games in the franchise. I'll be honest though I don't like a single other game in your wishlist. :P Seems more like a hatelist for me. :O

Sid Meier's Civilization VI & Dishonored 2
Those shouldn't be bad if you liked the previous games in series =d

I really enjoyed all Telltale games so far, so I'd rather go for that one. :)

I seem to be the only one, who liked Watch_Dogs, so I'd say WD2 and Sherlock Holmes

If it were me, I'd choose Civ VI. Civ V has been terrific and offers a great deal of replayabilty. You would definitely get the most bang for your buck with this game.

I personally would buy Deus Ex: Mankind Divided and Dishonred 2. Deux Ex: Human Revolution cautivated me instantly. The story really atracted and entertained me. The stealth with RPG skill tree and abilities, and FPS was really good. Plus it's cyberpunk themed <3. I haven't played the old ones. This sequel that continues the story, with the new technology that games are made with, should be an amazing game.
The same goes to Dishonred 2, but with steampunk in there, though the first had cyborg-ish structure in the story, this one has magic in it.

You should check Quantum Break that was released in Steam a couple of weeks before, but you most than likely saw it.

Shadow Warrior 2 and Civ VI
Two very different games, so if you get both you will have variety.

Civ VI - I love the series, and this one looks like a lot of very interesting innovation. Promises to be a notably different game in good ways - as opposed to the ways diehard fans of the series hated V.

Shadow warrior was awesome. Old school feel with new school gameplay improvements. The second looks like the first plus the money to do it even better.

I have some of these games in my wishlist, too!
If I had to choose one, I think I would choose Syberia 3. The reason is simply that I loved the first 2 chapters, so it's a sort of "must buy" for me when it gets released :)

1: Watch_Dogs2 (starts looking more and more like an actual GTA game + hacking, IMO that's pretty damn great)
2: Far Cry Primal (not a big fan of Far Cry 4, but this one seems really epic and original :D)

3: Tom Clancy's Ghost Recon Wildlands, not on your list but damn, that game is the first game since The Witcher 3 and GTA V to get me hyped this much (actually my number 1:P)

South Park The Fractured But Whole

The first one was hilarious, and I have the feeling the second one will be even better!

Dishonored 2 - First part was too good and so is the world it created.
South Park The Fractured But Whole - Humor and RPG combined. Who might require more reasons?

Dishonored 2 hypetrain!

South Park The Fractured But Whole
