You know it's really kind of amazing the amount of musical callbacks this game has.
Like the battle theme for Sur'kesh? It includes the same drums playing when you decide the way the ending will play out:
It's a very nice touch.
The way that your war room has a very quiet, very subtle version of Vigil's theme constantly playing is also very nice. It's hard to hear but it makes everytihng you do or say in there sound important, and weighted, and urgent, and sad.
