Gaming

The Great Giana Sisters (C64) Turrican (Amiga) Super Mario Galaxy (Wii)

There's a lot of them, but Hollow Knight's OST Dark Souls III, HotlineMiami 1/2 and Momodora Reverie Under the Moonlight are my favorites.

I love the soundtrack for the original Risk of Rain and also FTL

FF7, Ff10, Halo 3, Mario Galaxy, Persona 4

Gonna have to say this in no specific order because it's too hard to pick true favorites:

-Assassin's Creed 2

-Xenoblade Chronicles

-Pizza Tower

-Legend of Zelda Skyward Sword (or... any Zelda game but damn Skyward Sword and Twilight Princess are so damn memorable)

-Metal Slug 5

-Yakuza 0

And a lot more that I'm spacing right now.

The first Fable game has such an amazing soundtrack. Every one of those tunes is etched into my brain. They capture the feeling of the areas they play in so well.

Deus Ex Human Revolution & Mankind Divided

All three Splatoon games have really solid OSTs. I am also a huge fan of Hollow Knight. Deep Rock Galactic is amazing as well.

I love so many OSTs. They really make a game/movie/show

The Maxis Sim City game has a great OST from Chris Tilton. Quite partial to Riven and Hotline Miami too.

Honourable mention for Bastion too. And sometime I like the This War of Mine acoustic guitar stuff.

Cowboy Bebop, hands down. Oh, and Samurai Champloo.

The original quake soundtrack is great if "sound textures by Nine Inch Nails" interests you. Adding on to that, try the soundtracks for fan-made quake campaigns like Arcane Dimensions and Dwell.

I would say Halo 3: the music that play in the teaser triggered a HUGE hype instantly and because bungie delivered, the game has a special place in my heart, including the OST.

This year Baldur's Gate 3 OST is also about to be a banger (hope larian win the best score at the GA, even if it will be complicated with FFXVI OST)

Persona 4 and Xenoblade 2 are my top 2

Super Mario Odyssey - 1 UP Girl is a phenomenal song, and the rest of the soundtrack rocks as well. Bonus points for every track having an 8-bit version

Final Fantasy IV - My first SNES game. I still have that entire OST burned into my mind. The first time I heard the full orchestral version of the FF theme (I had played FF1 previously) blew me away

Outer Wilds - Better when heard in-game. I still tear up hearing certain pieces

Mega Man X2 - SNES era Capcom music at its best

The Great Ace Attorney - Really the whole series, but I think this one is my favourite. Capcom has great composers. The theme at 221 Baker Street is the coziest music

StarCraft: Brood War - Terran theme

Hollow Knight ofc, but also love Risk of Rain 2's OST, cyberpunk 2077 has a lot of bangers in there too. Unironically Spore has a nice soundtrack, but ofc it's better when you're in-game. Mass Effect has several bangers per game, especially love the OSTs of ME2 and 3. I love a lot of game music, especially when it's enhancing a moment in the game. Like in Spore when you're on the main menu with the spiral galaxy, or in ME2 when you're on the final mission. The thing that sold me on Cyberpunks OST was two fold: the radio stations are great, but the secret ending while listening to The Rebel Path is an adrenaline rush.

I looked over the whole list and noticed it's lacking one Rise of the Triad 2012 and Distance.

I would mention Rez and DJ Max, but it feels a little silly to mention Music based games for good OSTs.

And apparently I need to go listen to the OSTs for rain world and journey. They got multiple recommendations on here.

-Hardspace: Shipbreaker -Risk of Rain 2 -Gran Turismo (literally all of them, but 4 is a classic) -Super Mario Galaxy 1&2 -Ace Combat 4: Shattered Skies

Most of my favorites are already here, but one that's unfortunately overlooked is the soundtrack to Arcanum: of Steamworks and Magic Obscura. It's all this really moody, atmospheric string quartet music that just fits the game perfectly. I really recommend you give it a shot, it's really unique!

Chrono Cross is my favorite.

Dream of the Shore Near Another World makes me tearful every time I listen to it.

nobody has mentioned disco elysium? legendary soudtrack immo

Shocked and appalled at the lack of Resident Evil/BIOHAZARD representation.

The survival horror classics of the 90s are simply unmatched. One of my absolute favorites is the OG RE2's Marshalling Yard, both halves.

Granado Espada is a favorite classic and then there's Suikoden 2for the nostalgia

I didn't see it after scrolling for a bit, so

Hades

Absolute bangers. Along with everything else in the Supergiant lineup.

Really anything by Grant Kirkhope, Banjo Kazooie Yooka Laylee, etc, and on the Rare train, Donkey Kong Country 2 had great music.

Also love the Undertale soundtrack.

Persona 5 is my jam. Liked it so much I bought it on vinyl. Nier Automata is good too, more haunting and lends to the game's mood/ambience. I think Firewatch is like this too. Jet Set Radio Future and Persona 3 are also really groovy.

There's this french MMO i played as a kid called Dofus and that soundtrack still hits hard when I listen. I think part of it is nostalgia but also its just so beautiful

Legend of Dragoon soundtrack composed by Dennis Martin.

Bajo Kazooie soundtracks by Grant Kirkhope.

Donkey Kong soundtracks by David Wise.

Metroid soundtracks by Kenji Yamamoto.

All made insanely long lasting impressions where I could hear just a bit from one of the songs and instantly know what it is. Having played lots of video games, these seem to be the ones that have created the most lasting memory. They also absolutely slap as well.

The Legend of Zelda games BOTW and TOTK get mention here as well, though I don't find it as memorable. the sound design in these games is just top notch though.

Tetris definitely deserves a shoutout.

LA Noire by Simon Hale is fantastic though it's mostly just riffing off of Chinatown's soundtrack and I wouldn't say it really implants itself in the memory like the 4 mentioned above.

Other honorable mentions

Vice City

Jet Set Radio – Hideki Naganuma

Tony Hawk’s Pro Skater

Warhammer 40,000: Mechanicus

I also adore the OST for Octopath Traveler (even if I didn't like the game much)

Chrono Trigger and Chrono Cross will always bring me to tears. 💙 Also Robo's Theme is a banger!

I used to fall asleep to a Morrowind OST CD.
