The soundtrack would be slightly different depending what character you played. For a sega game that is pretty impressive.
This demonstrates how it changes with different characters.
Just mesmerising..
One of my favourites.
I still listen to the Skyrim OST now and again; absolutely stunning pieces by Jeremy Soule.
Other memorable tracks come from Bastion, Deus Ex: Human Revolution, and Braid.
I've also cultivated an affinity for Zelda's Skyward Sword OST, very stirring.
Surprised no one mentioned any Diablo 2 soundtracks yet? Also one of my fav's from Matt Uelman. Love the ambience and bleak jangley guitars. I've heard similar tracks while playing Torchlight 2, which is a plus. Still nothing comes close to Diablo.
