A slight improvement towards the Dying Light:

DLC Added:
Dying Light - Harran Inmate Bundle
Dying Light - Retrowave Bundle


DLC Still Missing:
Dying Light - Chivalry Weapon Pack
Dying Light - Left 4 Dead 2-Weapon Pack
Dying Light Book
Dying Light 3D Printer Models
Dying Light Original Soundtrack
Dying Light Collector’s Artbook
Dying Light Wallpaper Pack

I find it quite annoying that they add the paid ones but don't give a damn about the free ones.

Removed:
Craft The World. Grottoes dlc released.

Edit:
Dying Light.

And yes, still no Deluxe Edition for Dracula: Love Kills. But since Frogwares told me a while ago that they were thinking about a solution I decided to ask them about said solution. No reply. I bumped my message on facebook a few times ... no reply. Then I got a bit displeased ;) and told them how I don't like to be told something just to keep me calm and that they could at least be honest and that I can't buy any Frogware games now on GOG because ... and so on. And THEN they replied today (posted the other message yesterday, so make of that what you will). Here is the reply and it sounds much better!

"Hello , we are working on it."

So no more "thinking" about a solution but already "working". Imo if this would just have been PR BS they could as well keep ignoring me or telling me that they tried and weren't able to deliver. So imo this is a good reply. And so I am crossing my fingers once again and play the waiting game ... once again.

Speaking of "waiting game" - did anybody check if the actual Dying Light version has the "no German intro movie" bug finally fixed?

Thanks for letting us know :)

Funnily enough I've been thinking about this too lately and I actually messaged them via their website support page a couple of days ago asking if/when they were going to bring the deluxe edition here. So far, no reply. That sounds par for the course though with them.

However, thank you for reminding them again and let's hope that it does come here soon. Like you say, fingers crossed and we carry on playing the waiting game!

these fail every single time on galaxy
no other dlcs do

great service!

bought them via the website and installed them via Galaxy / had no problems. I guess it was caused on your machine.

Bonus discrepancies:
- Free Outcast 1.1 Soundtrack is 66 MB on GOG while only being ten times the size on Steam, so it must include more tracks or better quality version

youre tryin' to download 'em on galaxy rather than like just install 'em?

downloadin' they fail here but no others do
also!
on teh website version if you try an' download 'em you can but they're both weird lee split into two 5mega files each
somethang funky goin' on here

I just checked it. One file is unnecessary since it only updates ver 1.13 to 1.14 - don't ask me why GOG did not remove it yet. You only need the file "setup_dying_light_harran_ranger_bundle_1.24.1_(64bit)_(35438)" for the Harran DLC. It seems t0o be the same with the Retrowave DLC which I don't own.

can you download it on galaxy? somethang weird goin' on.
if its my putes fairy nuff. just seems weird everythang else is fine

Download Harran DLC on Galaxy 2 without any problems - just tried it.

I don't know about the other games, but the STALKER series haven't received a patch in probably more than 5 years. Did you actually check what the changes are? Because they have nothing to do with the game itself.

EDIT:
You're actually linking to SpellForce 2 Soundtrack. I don't see any soundtrack for Outcast 1.1 on Steam. Only for Outcast - Second Contact, which is missing on GOG.

And here is the changelog for the missing update:
https://steamstore-a.akamaihd.net/news/externalpost/steam_community_announcements/2587811707179901604

As i read on steam Spellforce Platinum edition is patched to a more new version but it's more broken as they kinda ruined the game with it's bugs. The gog version is still the better version since it isn't broken that much and is a lower version than on steam.

aaaah i am usin' not-2.
