- Ruiner's Reikon Games seems to be based in Warsaw.
- 60 Seconds!'s Robot Gentleman seems to be based in Poznan.
- Serial Cleaner's iFun4All is a sub-studio of Bloober Team, which seems to be located in Krakow.
- NecroVisioN & NecroVisioN: Lost Company's The Farm 51 seems to be located in Gliwice.
- Gwent -- unfortunately, this overlooked game was so poorly-received, it never even got past beta. The super-obscure development studio (who even remembers what they were called?) probably doesn't even exist any more at this point. (There's also the unreleased "Thronebreaker" DLC for the game.)
- Also, included with A.D. 2044 (which Grargar already mentioned) are the Polish-language-only Sołtys and Skaut Kwatermaster, both of which were also apparently produced by LK Avalon (likewise already mentioned in Grargar's last post).

Some other random things I noticed:
- The mentions of "CD Projekt" in the Witcher-related entries should probably include "RED", which is the actual dev studio within CDP.
- If you're trying to keep things alphabetical, The Vanishing of Ethan Carter should come before The Way. (Also, strictly speaking, The Witcher Adventure Game should come before The Witcher, but I can see why you might want to put the main series first.)
- Regalia is released (no longer "upcoming").

Also, nice video. :)

This War of Mine: Stories - Father's Promise (and the Expansion Pass that will give access to all future TWoM: Stories episodes) is made by 11 bit studios, who are already in the list for the base game.

Whoa, thanks for all the suggestions! I have added all of them and Observer too.

I've been really busy lately, also went to Finland and Estonia for the first time, so that's why I've been gone so long.

By the way, I gave up on trying to keep this alphabetical at this point. Until GOG comes up with an easier method to reorder GOGmix entries that's less of a hassle, it will have to stay this way.

Erm...I see you might have taken my deadpan irony regarding Gwent at face value. I thought everyone even remotely into PC gaming would be aware that Gwent is a Witcher spin-off being developed by CDPR (with help from GOG), and, while it IS in beta, it's not really "stuck" there. :P Sorry for the unintentional troll.

Oh, right, sorry about that. XD To be fair it has been so long since I properly sat down and played a game, I've grown a little distant from gaming in the past half a year or so due to other commitments. Still quite embarrassing for me though haha.

A handful of additions gleaned from one of the competing "made in Poland" GOGmixes:
- Seven: The Days Long Gone - Fool's Theory - Bielsko-Biala
- Frostpunk (upcoming) - 11 bit studios (mentioned elsewhere in mix)
...and, assuming you feel like adding a movie:
- Video Game Show — The Witcher 3: Wild Hunt concert - CD Projekt RED (no idea about the orchestra/other musicians or conductor, though, as none of that -- not even the composer(s) -- is mentioned on the GOG product page) - Krakow (Film Music Festival 2016)

Also, as previously mentioned, the developer of Gwent and its eventual DLC is CD Projekt RED (with some help from GOG for at least the base game, as Gwent is heavily integrated with GOG Galaxy). Sorry again for any confusion I caused on this.

Also also, a thought: you might consider omitting standalone soundtrack DLC unless the music therein was actually composed or performed in Poland or by a Pole. Though I can understand why you might want all of the ancillary content related to a Polish game included in the mix, lack of clutter can be good, too. :)

Added the above. Thanks!

I'm trying to add Cinders and the three versions of Solstice, all developed by MoaCube (based in Warsaw), but the GOGmix just eternally loads and won't let me save the changes. Would be great if an admin could look into this.

Thank you.

GOG seemingly have abandoned all attempts to fix their site recently. GOGmixes are only one of many broken things at the moment. You can join a group of optimists saying that it's a sign of a page/forum revamp. Or you could stay with us, grumpy bunch, claiming it's business as usual. At least we have more legitimate things to complain about...

Oh man, that sucks((

Thanks for the response though.

Tower of Time is from the polish studio Event Horizon and should be added anyway fine list of games on that mix.

Thanks, will add it now))

Nooo you won't. ;)
Apparently the old GOGmix code was so broken and incompatible with newer versions of the site that they just decided to scrap the feature entirely -- GOGmixes have been gone since last fall, and can only be viewed offsite as archived versions (if they happen to have been archived by the likes of the Internet Archive's Wayback Machine, which -- without checking -- I'd assume yours was). For now, your only option, should you want to attempt to carry on with this, is to recreate your mix here in the forum (or somewhere offsite, with a link to it from here).

Huh, well that sucks....

Thanks for letting me know though, as you can see I've been away from the forum for a while now heh.
