Icewind Dale: Kuldahar Theme.

It really makes you feel in that place.

The Witcher 3 soundtrack - memorable one.

For long time it was the old command and Conquer soundtrack but it has now become the SubNautica soundtrack. Just so relaxing to work with!

Definitely ICEWIND DALE soundtrack. Targos town score from that soundtrack was so dreamy and i felt that i was inside the game.Disconnected totally from the real world when i listened to that soundtrack or played the game. What a lovely score.

Definitely the soundtrack of Lucasarts Outlaws. Really serious music for non-serious(cartoonish) graphics. This artistic contrast between graphics and music adds an another dimension to the game. Especially last track Showdown is one of the masterpiece of western genre.

Definitely Diablo games, especially Diablo I and II. Diablo I was one of the first games that totally got me, and I've spent many and many hours playing Diablo II, with soundtrack on full volume.

Heroes of Might and Magic 3 - Necropolis town soundtrack
Such a complex, ambient and high quality soundtrack with mixed atmospheres. This is definitely my favourite of all time.

The best soundtrack in the game ?? Dungeon Siege has great soundtrack, but the best soundtrack is in Might and Magic VI - VIII and HOMAM III and IV series. And choose one of that ?

I choose HOMAM III and Might and Magic VI - The Mandate of Heaven.

Long live Paul Romero Robert King, Steve Baca and Jennifer Wang

Stellaris' soundtrack is one of the best in my opinion - it's melodic, emotional and does everything to make you fully immersed in to the game.

Ristar's music is great. It's otherworldly and sci-fi but never loses track of its childlike ambitions.

The original Heroes of Might & Magic II. The operatic, German score was beautiful, and each song fit beautifully with it's castle. There is lots of good video game music, but the original Heroes of Might & Magic II is by far the best.

Most memorable soundtrack for me would be Heroes of Might Magic II, especially Price of Loyalty Expansion. I even put the battle theme as my mail ringtone on cellphone!

Because the tone so magically true to the bone of the game. I appreciate the originality of Mr Romero's composition. The opera singers accompanied with some medieval light orchestra come to some distinct harmony.

Nonetheless I remember how I played it on my college friend's PC, since I did not own one that time. Ah.. what a goood ol' days!!

My most memorable soundtrack has to be the one for Age of Mythology, which has been with me ever since I first played it in 2003. It has such an evocative feeling to it, with a blend of modern and "ancient" instruments which really sets the mood of the game. I've used it for a lot of different things - creating an atmosphere for my D&D game, getting inspiration for my writing, focusing on assignments, work, painting, etc. Riding a bike late at night with "eat your potatoes" in my ears, or putting on the mellow mix of "never mind the slacks and bashers" as my D&D players find a scrying pool... it's amazing.

(Also the track titles. By Thor I love the titles)

Diablo II + LOD Soundtracks by Matt Uelmen.
The score complements the different environments perfectly, adding an extra layer of mystery, evil, suspense, motivation to explore... It really plays a crucial part on the overall storytelling.
Every time I hear it, it just makes me want to play the game all over again.

The most memorable video game soundtrack for me is the soundtrack for Skies of Arcadia.

This soundtrack has it all: bouncy hummable background music like Sailor Town and Little Jack, adventurous exploring of distant lands like Kingdom of Ixa'Taka and Kingdom of Nasrad, relaxing contemplative music like Theme of Loneliness and Theme of Reflection, tense battles like Jealous and Giga's Theme, and iconic themes like Vyse's Theme and Opening Theme.

It's just utterly fantastic; even if you haven't played the game I suggest you give it a listen. (Especially if you're a fan of music from open adventure games around the late 90's and early 2000's like Megaman Legends, Ocarina of Time, Final Fantasy VII, etc. or music from anime adventurous anime from the same era like Ghibli Films, Full Metal Alchemist, Inuyasha, or Eureka 7)
