With a two and a half minute main theme score who wants to even play the game? :P
And its pretty good aswell, i like how the progression glues to itself and doesnt stray wich gives a very threatening and glooming mood. Really crisp organ too, wish i had one of those.
I think the organ is actually from Garritan's organ pack. One of the garritan products that is actually worthwhile checking out. I've also heard some of their Instant Orchestra and it really sounds quite good, which is surprising.
