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…
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.
TUNIC, FEZ, Nier Automata, Outer Wilds.
I also have a soft spot for Paper Mario and TTYD, those soundtracks are full of bops
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 really vibe with Minecraft. The nostalgia just hits different when I listen to it.
Indie games in general have great OSTs, MGS:R and Persona (and SMT in general) are obvious popular picks.
The World Ends With You is less mainstream (with one of the few gripes being the lack of boss-specific themes, at least in the DS original I played - but it makes up with the diverse overworld and normal battle themes), as is Etrian Odyssey.
I think orchestra is mixed, it’s either the best fucking tracks ever (often when mixed with electric guitar, but not necessarily), or they kind of blend with other orchestral tracks I know and don’t end up being unique enough to remember.
NieR: Automata
The Weight of the World
Final Fantasy VIII holds a special place in my heart for sure.
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.
Nier automata has a great soundtrack, i haven’t played the newer one yet, but Drakengard 3 has some great songs on it, if you haven’t played it its meant to come before nier world lore wise.
Also gotta give a shoutout to World of Warcraft, got some massive nostalgia from that soundtrack
I actually got Drakenguard 3 running on my steam deck recently, it runs surprisingly well. I could immediately tell the game was gonna have great music based on the opening animation.
I find Nier replicant is good only after you make it past the first one or two hours. Too many fetch quests for me.
I will say drakengard 3 was one of the grindiest games ive played haha, dont wanna spoil anything though so thats all ill say. But its worth it the story is good if you like yoko taros type of storytelling. Theres a 60 fps patch i used but idk if steam deck is good enough for that, my old pc could barely handle it at 60fps with an i5-6600k and rx480
I think the Elder Scrolls games all have great music, but Morrowind’s OST has always stood out as amazing. Hearing that opening soundtrack immediately sends me back to playing it for the first time!
All-timer has to go to Chrono Trigger. Absolutely incredible soundtrack from start to finish.
I like epic, intense soundtracks so, Darkest Dungeon and Frostpunk. Monster Train is pretty good too.
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
Doom (2016) and Doom Eternal have amazing soundtracks!
Mass Effect 3 OST has seen it’s fair share of play time as well though that might be just as much because I love the game so much.
Oh! Cyberpunk 2077 is amazing as well. Especially the songs from the radio stations in the game.
