Personally, I’m a huge fan of Hollow Knight, Ori and the (Blind Forest/Will of the Wisps), and Kingdom Hearts. Orchestral soundtracks are just something else…
TUNIC, FEZ, Nier Automata, Outer Wilds.
I also have a soft spot for Paper Mario and TTYD, those soundtracks are full of bops
Outer Wilds. Yeah it’s one of the greatest games ever made, but would it be so good without that soundtrack? Debatable.
I petitioned to play something from it at my actual wedding (sadly was overruled), and I know I’m not the only one.
I know! It’s such a good ost! I think one of my favorite songs for it, although not from the ost, is Andrew Prahlow’s Outer Wild - Reprise single. It’s got aspects of all different main themes and is just overall an amazing piece
I can barely make it 30 seconds into that one without tearing up and I’m not ashamed to admit it.
Was looking for someone to mention Outer Wilds. I love when games weave music into storytelling and its perfect here.
Ori and the Blind Forest’s ost is phenomenal.
I think all of the Supergiant Games have great soundtrack. Transistor was what got me into their games, and it was the soundtrack that caught my attention first.
I like epic, intense soundtracks so, Darkest Dungeon and Frostpunk. Monster Train is pretty good too.
NieR: Automata
The Weight of the World
Transistor
Katamari Damacy
Stardew Valley
Finally someone mentions Transistor!
I saw Pyre in another comment and honestly, I’d just go ahead and say everything Supergiant has made has top teir OSTs. Bynn the Breaker and Zia’s theme from Bastion, In Circles and The Spine from Trainsistor, In the Flames and Bound Together from Pyre, In the Blood and River of Flame from Hades all incredible songs. Supergiant has too many bangers to list across everything they’ve made
All the soundtracks Darren Korb makes for Supergiant. Hades resonates more with me as it’s the one I’ve played the most, but I’m also a huge fan of Transistor’s.
Both the Nier games have amazing soundtracks that I listen to frequently.
Kena: Bridge of Spirits is also great although I don’t really listen to it on its own. It really makes the game feel much more impactful while playing.
While there’s no correct answer here, I think the most widely beloved OSTs of all time probably belong to the Final Fantasy, Donkey Kong, Legend of Zelda, and Super Mario IPs.
Endless Space 2. The best OST I have ever come across in 20+ years of gaming. Several hundred hours in and I’m still not sick of any of the tracks.
Bastion and Hades have just cool soundtracks you can listen to anytime. When pure adrenaline is needed the DOOM soundtrack.
XENOBLADE CHRONICLES 2
Yes, let me list some of my favs! This is generally starting from my fav, but it’s not strictly ordered.
Counterattack
Driver VS
Monster Surprised You
Gormotti Forest
Battle!!
Exploration
Still, Move Forward
Battle In The Skies AboveI also adore the OST for Octopath Traveler (even if I didn’t like the game much)
Octopath Traveler Songs
Sunlands
Battle 1
Battle 2
Boss Battle 2
They Who Govern Reason
The One They Call The WitchLet’s not forget the prequel to this and all the bangers that game has!
All-timer has to go to Chrono Trigger. Absolutely incredible soundtrack from start to finish.
Man this question isn’t even fair there are so many fantastic soundtracks in gaming I could literally go on for hours about them.
Doom, Mass Effect, Halo, Skyrim, Ratchet and Clank, Assassin’s creed(3 especially), Divinity original sin 2, pathfinder: wrath of the righteous, monster hunter, league of legends(all of riot games really), darktide, sonic, payday, witcher, Spiderman, Zelda, cyberpunk, megaman, final fantasy, Devil may cry, metal gear, undertale
that’s just what I think of off the top of my head, there could easily be an entire sub just dedicated to the topic
Finally! Someone mentioned Undertale.
