Not exactly answering the question, but hearing every generational rendition of Proof of a Hero throughout the Monster Hunter games still gives me the feels

For me definitively the soundtrack of Boneworks (which is also the best VR game I know). Especially its main theme ("Bone Theme") and "Who am I"

Some more awesome OSTs in no particular order: Minecraft, Banjo-Kazooie / Banjo Tooie, Witcher 3, Risk of Rain 2

Wingspan. I have the Vinyl OST.

Monument Valley is quite nice too.

I still listen to the NSFU2 soundtrack today when I feel the need for a bit of hard hitting sound, with some variety.

I'm going to go for a bit of a deeper cut and say Mad Rat Dead. They took a genre which relies so heavily on the strength of its music (rhythm platformer), and produced a soundtrack where literally every song is a banger, and produced some great emotional moments as well--the transition from Cottage House to Kind of Hope and Neuchatel still makes me choke up just thinking about it.

I'm a big fan of the Offworld Trading Company OST.

Tony Hawk was a big one. The EA sports games always have some bangers that get stuck in your head. One of my favorite video game moments, though, was bombing the tobacco fields to Bomba Estereo's "Fuego", in Far Cry 6. They employed music well, throughout, but that moment was really enveloping.

My pick for best chiptune track

Haven't seen it mentioned, but, Spiritfarer

Mario 2.

Samurai Shodown series has an amazing soundtrack. A mix of traditional Japnese sound, rock music, chaotic jazz, and ambient sound that barely resembles a song. The ending of 3 is my ultimate 'get pumped' song:

Star control 2 was the absolute best imo

Hughe fan of the low roar songs in death stranding

half life franchise (seriously every game has perfect and fitting soundtrack) super meat boy (both the original 2010 soundtrack composed by danny b and the 2015 soundtrack made by various artists rock. but the 2010 soundtrack is one of the most iconic soundtracks ever made in my opinion.)

Modern Warfare 2 (2009)

Left 4 Dead

Warcraft classic - TBC - WOTLK - Cataclysm

They are Billions

Your reality is amazing

Risk of Rain 2

Castlevania, Zelda and Silent Hill (though I'd say all first 3) mentioned so I'm gonna say Alundra. Sure it's very Zelda/JRPG, but that game had some amazing music that just sticks with you.

Also a little tongue in cheek, but Adventures of Lolo. I'm not sure if there's just one song throughout the trilogy, but it sure feels like it. Weirdly it doesn't bother you. It's like a hypnosis that just makes you play one more level. One more try. Kind of like the Tetris soundtrack, but it never gets old.

Shadowrun for Sega Genesis

This is going to be highly subjective.

For me, this may not be the best, but it's one of the more memorable soundtracks.

Star Wars Knights of the Old Republic, Manaan theme. https://youtu.be/CNe4XHbkEZA

I'm going to give honorable mention to Buck Bumble on the N64.

I remember basically nothing about the game, or even if it was any good, but I rented it once at blockbuster and like 2 decades later the theme song still pops into my head once in a while.

Tenchu: Stealth Assassins

I played a beautiful game last year called Omno, and the soundtrack to that was just breathtaking. I listen to it all the time

Hands down, DOOM Eternal

@TheBananaKing

I'd say Sayonara Wild Hearts. It's a rhythm game so expertly crafted with the musicsoundtrack it gives me chills. It's so, so good

My favorite is Dragon Age Origins, personally.

The really cool war chant for the Ostagar scene, Lelianna's Song, and the soundtrack of the Brecilian Forest are my favorite.
