Some of my favorites are older nintendo 64 games like Bomberman 64, Megaman 64 but then I also love Martin O' Donnel's work for Halo especially ODST. Others I actually own on CD are Mass Effect, XenoBlade Chronicles X, Persona 4
I just you know what game I'm in to. (P••e••n)
squaresoft has made some awesome final fantasy compositions, but here is one song I love so much. I can listen to it forever:
It's in a made-up language. Beautiful composition and singer. It makes the hair on my neck stand up when I listen to it, it's so beautiful. I think this song has the ethereal ability to heal pain just by listening to it. It's one of my favorite songs of all time.
Nostalgia is unreal with COD4: Modern Warfare
I couldn't possibly choose one track or even one game, but I do have a favorite composer, Yuzo Koshiro.
Favorites would have to be:
Chrono Cross <--- probably my favorite video game soundtrack
Mother 1, 2, and 3
Lunar Silver Star
Sonic Adventure 1 and 2
Sonic CD (Japan)
Streets of Rage 1 and 2
Just about anything Sonic. The franchise hasn't been strong in a while (although Sonic Mania and that Sonic Generations one coming out look freaking awesome), but I think most of us can agree that series has a ton of the greatest gaming music known to humankind.
Hell march. I have never experienced another track that fitted a game so well.
Persona 3, Persona 4, Digital Devil Saga 1 & 2, Devil Summoner: Raidou Kuzunoha, Shin Megami Tensei III, etc. just about any Megami Tensei title or random game put out by Atlus has an amazing OST. Mostly because of composer Shoji Meguro.
Mana Khemia, Atelier Iris, and Ar Tonelico have like the best OST I've ever heard.
