I have this on my Steam Wishlist and am right on the brink of purchasing. I take it your post means this game has an over arching storyline that ties everything together. Is that true?

I just have a question.
Does the soundtrack contain the classical music from the radio, and if not, what is it called and where do i find it.

That guide is actually quite useless as it's mostly untranslated and it's also very incomplete and unorganized.
Why are you suggesting such a crappy guide to us Kezarbash?
