Celeste and Pokemon mystery dungeon explorers of sky

TF2

Teenage mutant Ninja turtles iv: turtles in time

Definitely the best video game music is from Metal Gear Rising: Revengeance. Stains of Time is my favorite.

For ambience, Anarchy Online.

Final fantasy 6 Chrono trigger Street fighter 2 Street fighter v Super Mario Bros 3 Mega Man 2 Undertale And this is really unfair but Def Jam fight for New York

Jet Set Radio Future and Jet Grind Radio. No question. Hideki Nakanuma is a genius.

Oh and Dance Dance Revolution 3rd, 4th, and 5th miss.

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.

Not sure about best but the music the black mesa game did for the half life remaster was amazing.

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.

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

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.

Mega Man 3 on guitar is fantastic: https://youtu.be/9__sJWMXjE0

A few i havent seen mentioned.

Sonic 2 and 3 on megadrive. Especially the ice zone with the snowboard on 3. https://youtu.be/hYxlqTpZ-24

Icewind dale. The kuldahar music is epic. https://youtu.be/B92P1-OUNJo or easthaven in peace https://youtu.be/ERd5stTsaBc

For me personally some of my favorites (most memorable) are:

Hitman 2: Silent Assassin main title (and first half of the OST)

Divinity Original Sin 2 main title

Original vanilla WoW main title music

Sanctuary from Borderland 3’s OST

BFG Division from DOOM

Pretty much the entire Skyrim soundtrack

Most of the Witcher 3 soundtrack. My favorite is probably On the Champs-Désolés, which is from the Blood and Wine expansion.

I listen to "Carmeaty Burana" from Super Meat Boy all the time.

Pretty much any Danny Baranowsky is gonna be good.

Your reality is amazing

Deep Stone Lullaby fro the Deep Stone Crypt raid in Destiny 2.

It’s an absolutely beautiful piece of music, but so much impactful more when tied to where it appears in the raid as you battle your way across the underside of the space station, all of the other sounds muffled by the vacuum of space.

I don’t know who the guy is, but this video of DrLupo playing it with an orchestra playing the track live while he does is pretty damned amazing.

Total Annihilation

Unorthodox opinion here but Wasteland 3, the first time the Battle Hymn of the Republic played over a fight was incredible.

There is a reason Touhou has two fandoms, one for its games and the other for its music. The music alone saved it from being another Oregon Trail and eventually got it its own anime.

Haven't seen it mentioned, but, Spiritfarer

Underwater theme from donkey Kong country

Really really obscure but I could never take this song off my head, from A Thousand Arms, psx game. Game was a goor jrpg.

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:
