Best soundtrack in the game

Tom Clancy's Splinter Cell: Chaos Theory OST by Amon Tobin. Fell in love with Amon's music after :). I think it was first game with situation based music that I played (if you do some stealth - chill music playing (w/o drums), in action - intense/loud music playing). Also cool that same track playing on one location (for stealth and action scenes).

I’m not a music critic, I just want that you yourself have introduced that there is beautiful music and that there is a fake that you will be provided with on different polls, in fact the site is very large, let the best be here!

Beyond Good and Evil, obviously.
I'm also rather fond of the Final Fantasy VI soundtrack.

Hey hey people!
Underrail: expeditions gray army base OST https://www.youtube.com/watch?v=qzVexHHhh4A

And for an actual old game, "Heroes of Might and Magic 3 : Combat 2" https://www.youtube.com/watch?v=WbK-qyObdXM&feature=youtu.be

Neverhood soundtrack

First one that come into my mind is everything related to sims1, especially the makin magic expansion ones

And Iron Grip Warlord is the kind of music I want to hear in everywhere, I like the style a lot

Epic Loon by Pryapisme

Lind Erebros - Under the shadow of the oak https://www.youtube.com/watch?v=l-DXMCYTiDc

The first PC game I've ever played also featured the best game music I've ever heard. It's still Terry Taylor's OST to The Neverhood.

Also, can't but mention music by Robert Holmes (Gabriel Knight 1-3, Grey Matter).

MGS - Snake Eater

Two words - Brutal Legend!

deus ex human revolution and mankind divided
darksiders 2 <3 <3
tomb raider legend and anniversary
mass effect 3
devil may cry 3 and 4 even DmC lol
painkiller 1

I know it's not the best, but I really love Shovel Knight's soundtrack.

Frostpunk

"The City Must Survive"

Diablo 1 - Catacombs theme.
It's not very melodic, but it's hellishly dark. After all these years I still remember that crazy laughter and baby cries.

.#1 obviously Cannon Fodder intro - https://www.youtube.com/watch?v=PiYuq6Ac3a0
2 Red Alert soundtrack - https://www.youtube.com/watch?v=yGgnywWO6Ts
3 dungeon keeper ost - https://www.youtube.com/watch?v=O6iHgOEp0Fg (i dare you to listen it at night, in dark room, playing some spooky game-or play original DK if you didnt already)
4 total annihilation ost - https://www.youtube.com/watch?v=ljDyp__ejco (not many will like it, its mostly orchestral music)

The soundtrack from The Cat Lady is freaking amazing. Not something that I expected, but dang...just so incredibly perfect for that game.

Commandos 2 and 3 have the best soundtrack in my opinion. https://www.youtube.com/playlist?list=PLU9VMAntXfvh9E7WwhFrhqckNomBwfKq-

The DIG.
Still my favorite point-and-click adventure game to this day. The wonderful alien world, memorable characters, and hauntingly beautiful soundtrack all came together to form something really special.

Chrono Cross - pretty much everything
