Heh, just a few on the go: Witcher 3 Cyberpunk 2077 Divinity: Original Sin 2 ("Sing for me" 🥰) Battlefield 1 and V Hi-Fi Rush

The songs from the first Life is Strange just hit different. Paradise Killer OSTs are also bangers

These:

Chorus is an underrated game with an amazing main theme

KOTOR and KOTOR 2, Mass Effect (Vigil, Leaving Earth, An End Once and For All), Hogwarts Legacy (very reminiscent of the movie scores but its own thing)

Legend of Heroes has many of my favorite soundtracks. Hard to pick which one is my favorite because so much of them are absolute banger

Visual Novels usually have pretty good OSTs, such as Danganronpa 2 and Umineko no Naku Koro ni

Wild for me to scroll through a thread like this without seeing Halo: ODST mentioned.

Deus Ex and Oblivion

Warhammer 40,000: Mechanicus has a really cool, cyber-gothic OST.

Steven Wilson’s soundtrack to The Last Day of June is absolutely spectacular.

Mega Man X for SNES is one of my favorites. In the PSP remake, the re-recorded all the original 16-bit songs with live instruments. It's amazing.

There's some stuff across the Metal Gear Solid series that's pretty memorable.

Primarily a mix of Old School RPGs (FFVI, Secret of Mana, Chrono Trigger) and some current RPGs (Persona 5, NieR: Automata)

I see several people naturally mentioning the Minecraft OST, there are two resource packs I highly recommend if you want a more nostalgic experience.

• "Balanced Music" is a great pack on Modrinth that removed the biome specific criteria and re-balances everything so you do not keep hearing the same caves & cliffs song every 10 minutes.
• "C4Music" is another pack on Modrinth that removes the newer tracks (post Nether update if memory serves me right) and only has original music + some of the unreleased tracks.

To answer the question myself though, other than Minecraft of course I would have to say Terraria, OpenTTD, Ocarina of Time, RimWorld and Celeste among many other titles.

Far Cry 5. It's probably the only game I've played that has the same songs written in totally distinct music styles. Each song, like "We Will Rise Again", is written as:

• A church hymnal (men and women's mixed chorus)

• A folk song (bluegrass inspired, fiddles, acoustic guitars, and steel harps)

• An ethereal rendition by Hammock that evokes the "bliss" part of the game world that the character Faith rules.

It's amazing that all three of these songs are the same in lyrics and meaning, but their execution is completely different and had very different emotional feels as a result.

• Ico
• Final Fantasy XIII
• Final Fantasy XIV
• Stellaris
• Warhammer 40k: Darktide
• Kingdom Hearts
• Mirror's Edge
• Modern Warfare 2
• Need for Speed: Most Wanted (OG)
• Ratchet & Clank
• Halo 3: ODST
• Persona 5

For me it has to be a mix of doom 2016 the witcher 3 and chrono trigger. So many good soundtracks between them.

Child of Light, Hades, Bastion, Icewind Dale, Dragon Age (any of them really), Heroes of Might and Magic 3-5, Dead Cells, Endless Legend, Pillars of Eternity, Pokemon Violet. Also Warframe, especially from The Second Dream and further period.

Star Ocean 3, Yakuza: Like a Dragon

I was completely obsessed with the Final Fantasy 6 sound track as a kid and even did a playthrough with a tape recorder to make my own sound track.

Chrono Trigger is a close second.

I want to throw out an honorable mention to Dust Force, the sound track may be some of the best "get into the zone" music I've ever heard.

Crypt of the Necrodancer and Cadence of Hyrule both require me to stand, so I can bounce in time to the music with my character.

Bastion, Beyond Good & Evil, Prince of Persia: Warrior Within.

idk if this counts as an "OST" but the New Vegas soundtrack like changed my life lol. the vibes set by those choice cuts of big band/swing from the era just added a level of immersion and comfort I didn't even know existed.
