What is your favorite Game Soundtrack.

NieR

Legend of Zelda: Wind Waker (all of the songs)

Geez, if I would list them all, I'd still write after 24 hours... I love game musics (yeah, I find them much better for myself, than actual songs), and there are a lot, that I listen.

There's so many game soundtracks I could list, it would be ridiculous. The one I've most recently listened to is the Chrono Cross soundtrack.

Time's Scar.

Braid and Bastion

Legend of Heroes - Sora no Kiseki the 3rd

Really, I love all Falcom game soundtracks and the channel that comes from has them all uploaded, but that one is overall the best. A few highlights:

Genuine Devil
Overdosing Heavenly Bliss
Castle of Illusions Phantasmagoria

Battlefield 1942 (Best FPS soundtrack ever for me)

And obviously Bastion:This and This

Commenting since I somehow stopped 2 soundtrack playlists to listen to this, the Hype overwrites focus, Metal Gear Rising Revengeance THERE WILL BE BLOOD, SHED :3.
Also just post some people, no need to list them all, or none :D, just share the awesomeness, I love the ones posted so far.

Hotline Miami has a beast soundtrack, also Vice City and GTA TBOGT Electro Choc radio station

Almost any Silent Hill theme

Double Dragon Neon.

Super Castlevania IV
Mega Man 2

Super Meat Boy; The Binding of Isaac; WORLD OF GOO (masterpiece); Half-Life 2

NFS 3,6, AoE 1/2, HL/HL:Of

Bastion, World of Goo

Burnout 3, Burnout Paradise and DiRT 2.

Bastion, Shadow of the colossus, and the first three crash bandicoots

Jamestown.

Not because its amazing music but more for the nostalgia of it has to be Sonic 1 and 2.example.

Freedom Fighters
Guilty Gear X2
Unreal Tournament
Fallout 3
Warcraft 3
Starcraft
And, sometimes, Warhammer 40k Dawn of War - Soulstorm.

Bastion, Dragon Age Origins

FTL

Anodyne, Final Fantasy X and Nobuo Uematsu in general, Umineko no naku koro ni, probably a lot more that I can't think of right now.

Soooo many... Anodyne, Bastion, any soundtrack made by Danny Baranowsky, Sword & Sworcery, Hotline Miami, Dustforce, They Bleed Pixels, Super Hexagon, Thomas Was Alone, Awesomenauts... do I have to continue?
