Their has been brilliant ones such as Halo, Dragon age, Civ 4, fallout new vegas, Farenheit, Morrowind, but the one that stood out for me the most is the Zone of the enders menu music.
It makes the hair stand up from my back every time, so chilling.
I seriously don't understand why it has been four pages, and no one has mentioned it. Yet people mention rubbish such as Mass Effect 2's menu music, just because they are a Bioware fanboy.
I'm Disappointed Escapist.
Edit: EKOS mentioned it at least, but his video isn't properly linked.
