I might make a full list later on but i just wanted to say the original Ratchet and Clank trilogy had an amazing soundtrack.

hmm..no particular order:

Child of Light
Moonlighter
Valiant Hearts
Rayman Origins
Xenoblade Chronicles
Shovel Knight
Starcraft
Earthworm Jim 2
Pokémon Red/Blue
Donkey Kong Country Tropical Freeze

Honourable mention to Tokyo (Shin Megami Tensei IV)

Super Mario 3D World. I think this is the most balanced of the main Super Mario soundtracks, it combines both the whimsical, energetic side of Mario with the epic, more atmospheric side of it, it has a good deal of variety, while also remaining memorable through the game.

Tales of Symphonia. I find this to be the best of the Tales of series, it stays consistent across most tracks, and it doesn't suffer from an issue of modern Tales of games of the melody and tempo being drowned out by generic orchestral instrumentation or very low melodies across what could be pretty good tracks otherwise. Phantasia and Vesperia are also up there with Symphonia's score.

Atelier Ayesha: The Alchemist of Dusk. It strikes the best balance of having variety and memorable tunes, it keeps the happy style of a lot of Atelier songs, while also adding a more melancholic batch of songs to it to represent the Dusk quite well.

Pokemon Sword/Shield. Gen 5 music but even cooler. Slumbering Weald is one of the most beautiful Pokemon compositions ever made and the Champion theme epitomizes the entire game and franchise for me with the best use of one of the main themes of the series.

The Legend of Zelda: The Wind Waker. Adventure!

Xenoblade Chronicles X. Papa Sawano, some things just create a perfect harmony, and I can't think of a more fitting score to the alien planet of Mira than this, title screen greets you with a mix of electronic alien sounds with the orchestral instruments building up the scale of it all and it maintains that sense of sheer epicness and adventure through the entire game.

Toby Fox (Undertale/Deltarune/Little Town Hero). He can do anything.

Donkey Kong Country Tropical Freeze. Much like every level of Tropical Freeze stands out, is all supported by a track for every level, all peak David Wise.

Paper Mario, the Alpha.

Paper Mario: The Origami King, the Omega.

64 and Origami King share things in common, both are big soundtracks that never falter in quality, other scores are smaller, or have a handful of tracks that don't stick the landing as the rest does, these two Paper Mario games don't fall on that in their runtime, a lot of areas have multiple themes across the board, plus a lot of one off tracks that are used for a single moment and the like, variations for the hubs and in the case of Origami King, for battles as well. The original Paper Mario is an impressive soundtrack that gives a different touch to a traditional Mario adventure, Origami King is an impressive soundtrack that keeps the spark of Paper Mario while also taking the music into very non-Mario territory and it comes out being what may as well be my favorite soundtrack of all time.

Video game music is something I feel is pretty important for a game, which is why games that go with an atmospheric approach (BotW, I'm looking at you) leaves a lot to be desired.

Looking at individual songs is very different than looking at an OST as a whole

The Wind Waker
I'm part of the minority that really enjoys sailing, largely due to The Great Sea playing in the background. A lot of stellar tracks overall in this game

Tales of Symphonia
The OST overall is fantastic, with new battle and overwold tunes as you progress through the game, something FF and DQ could learn from. Is one of the few games where I listened through every song in the whole soundtrack

Super Mario Galaxy
This was the first time I've ever heard an orchestrated sound track in a video game, and it truly makes all of the difference

Xenoblade Chronicles 2
Arguably the best OST in my opinion. So many fantastic tracks, with very few songs that I actually dislike

Dragon Quest XI S
Just take the best songs in the whole franchise and orchestrate it. What can go wrong? Spoiler: it doesn't, but a decent amount of the new music introduced in this game isn't great.

Final Fantasy 12: TZA
I heard half of the tracks through FF Tactics A2, so the original soundtrack definitely holds up especially when remastered

A Link to the Past
Despite not having any nostalgia for this SNES game, the soundtrack holds up extremely well even today

Fire Emblem Echoes
Sort of have to have a Fire Emblem rep, and this one definitely takes the cake

Etrian Odyssey Untold 2
Remastering the already spectacular soundtrack of Etrian Odyssey 2 just makes it even better. Not a huge fan of the battle and boss music though

Insert rhythm game here
Can't beat a collection of great music
