My favorite soundtrack on GOG? Sacred Gold. A nice, atmospheric soundtrack for an wonderful, well underrated gem of a game.
If I could I would pick Enclave which is unfortunately not available...yet. ;)

Immediatelly arrive to mind, unhindered, memories of Braid, Aquaria and The Witcher as games with musical scores so important to the visual experience that settings for audio could be placed on the graphics tab.

But if video games are the artform that syphons-in all other types of artforms (sculpture, music, painting, theatre, literature, etc.) to be distilled into itself, then the best possible answer to the question of which OST is the best for a game must be: Which OST of a game is the Game.

Of the two choices I have (Metronomicon being the other), I put forth that Crypt of the NecroDancer ( https://www.gog.com/game/crypt_of_the_necrodancer_danny_baranowsky_soundtrack ) has to be the best OST and game possible.
Music and mechanics harmoniously fused together in a perfect tango (or dub-step, or techno, or mambo) of videogamey fun.

Furi, the OST is very significant to me, since this game came to me at a moment in my life that i needed, and the story of that game resonated in me, and something that is kinda special of that game, is that the music is a big part of that story.

Also, im a lover of hearing my music in vinyls, not only for the quality, but something about all the experience feels more intimate, beginning with cleaning the vinyl, the sound it makes when the needle touch the surface of the disc, its an experience of its own.

Sorry about my bad english by the way

How do we escape our nature? Humankind has grown beyond its confines to cover the stars, but still it is embroiled in its petty struggles. For all our vaunted development we remain a subject of our own foundations. It would be folly to ignore the animal in us, but we must confront it, not let it rule us. It's pretty clear the anthem of our movement, then, must take the first spot on the list: mentat Stéphane Picq's music for Cryo's Dune. The danger here is that now the animal is given flesh: we have no choice but to hear its cries. The test comes when we feel the urge to nod our head to the Worm Intro

It would have to be the soundtrack to Syberia.

Mostly because of that beautiful, haunting opening theme. It's a melody that can sing in my mind for days after hearing it.

Most game music is forgettable, made to work in a spesific setting, and not to be listened to separately. But sometimes something comes out that can stand on it's own. Syberia is one of those.

My favorite soundtrack on gog.com ? BRAID. It's beautiful and unique.

•Favorite soundtrack on GOG?
-Awesome, lots of my favorite games are on GOG. Let's see here....
-Hmmm...this is harder than I thought. Lots of my favorite games here don't have their soundtracks available.

Okay, looking through my games, I'll have to say the soundtrack I currently enjoy the most is The Witcher 3. The music enhances the brilliance of that game!

•Honorable mentions:
-Tyrian
-The Cat Lady (my favorite is either Inside or Forever)
-Neverwinter Nights

•Soundtracks that need to be here:
-Ultima 7
-Elder Scrolls III Morrowind
-Monkey Island

•Favorite soundtrack of a game not on GOG (but hopefully will one day be)
-Nier: Automata

Oh, it has to be Transistor. Yeah, the game itself is great fun, but the music makes the experience: haunting, ethereal, the music in this game has stayed in my head long after I shut down my computer. Transistor's music is the best argument I've heard in ages for why video games are truly an art form.

I don't know the composer's name. I don't know whose voice sings those transcendent songs. I don't know how many times I've just sat there with my finger pressing the Tab button so I could hear my red-headed heroine hum, but I do know this: often, I play Transistor just to have an excuse to hear the music. It's that beautiful.

I love Marcin Przybyłowicz's and Percival's work in The Witcher 3. It has been stuck in my brain since the release of the game. I humm it during my everyday life, my work. Even while playing other games, during combat I'll break out "Silver for Monsters".

Whenever topics about composers come up, I just cannot leave out Kai Rosenkranz and his magnificent work in the Gothic series. That is another great composer whose work has stuck with me for 18 years now... wow.

Quake.

Some of the best atmospheric tracks in any game ever, and all done by Trent Reznor. I've put some of that music into playlists and unintentionally spooked myself before.

PaRappa the Rapper and PaRappa the Rapper 2

because, I gotta believe.

I agree, the Quake soundtrack is one of a kind in the way that it can feel like you somehow get posessed by it but it can also be a meditating and soothing experience, which hasn't been matched by any other soundtrack I know of yet.

My vote goes to a more lighthearted soundtrack though, which is the OST of Rayman 2.
In contrast to Super Mario 64 for example the soundtrack has a much deeper, ambient and mysterious vibe to it, which really helps to suck you into Raymans world.

Like the atmosphere of the game, the tracks range from more upbeat to haunting.
Every tune seems to pinpoint match the situation and makes you associate the music with the moments of the game in your memory.

The game is accompanied by this soundtrack dynamically, so your actions will be underlined by certain passages, which kinda gives the music an interactive feel.


The Rayman 3 soundtrack is great too, but had an often more humorous approach and went a little more into the background, because the characters where fully voiced now and were talking during gameplay too.

I still hope there's a proper Rayman 4 coming someday!

There is many great OSTs. Cat Lady or Pathologic would be my first pick, but Kholat is the first of the best for me, because of Zeitgeist adventure path for Pathfinder (D&D) I played with my brother - we played alone, but it never bother us, we were switching the DM role. The whole adventure path took us a few years to finish, but every session was memorable (with a support of carefully picked music :)). As DM I used most of Kholat OST for the final adventure. The final part was masterpiece and the Kholat OST fits just perfectly! I saved the track Farewell for the final big scene - it was really unforgettable experience. Unfortunately, there is not enough time for playing now, but Kholat OST still hides some wonderous associated memories for me. :D

Personally, I'd choose the Hollow Knight Soundtrack by Christopher Larkin

The compositions for Hollow Knight meld themselves together with the game's stellar presentation (art-wise and animation-wise) in a way that brings atmosphere to its world and set-pieces, making them feel truly organic and immersive. Also, some tracks make the boss fights (and even some lesser fights!) feel epic, engaging and memorable.

Outside of the game world, the soundtrack's mostly melancholic yet calming nature (thanks to the use of classic instruments such as pianos and violins) makes many of its tracks perfect for both studying and sleeping.

My favorite track for sleeping... is "Dirtmouth".

My favorite track for studying... is "City of Tears".

My favorite track for some adrenaline... is "Hornet".
