I have acutally been listening to the new theme all day today. Here is my take on it.
The DAO soundtrack was perfect for that game. It had this lonely, mournful sound to it that fit the tone of that game. In the story, you are rather isolated, no matter what your orgin story was. Cousland grieving about family, Dalish elf separted from the clan, mage at odds with the world, etc etc. The music resonated that lonley quality. In the game, sure, you recruit folks, even romance folks, but I always felt strangely alone in it. Then, at the end, escpecailly if you chose the ulimate sacrfice, that music is running through your mind as you do it. You were the warden, and your story was meant to be bitterweet. Dying young to save the world.
DA2 was a little different, a different tone. You were a hero by accident, just a person trying to help your familty out. But the world is on the brink of craziness and you get caught up in it. I always felt that the music didn't quite fit that game, that it should have been less mournful and mysterious and more exciting. But in general, it was a rather shallow game, so maybe the music was too good for it, really. it was too similar to DAO's, but the overall tone of the story itself did not measure up the music.
DAI's soundtrack is friggen epic! And it goes away from the sad, lonley sound of the other two. But from what I can tell so far, it should. This game is about leading armies, after all. It is about saving the world, but not having to do it all alone or against all the odds. You have power in this game. Lots. And you are trying to save the world. The music has me pumped for it. But even still, even with that epic sound, it still has those little bittersweet notes, particulalry in the beginning. I think it hints at tragedy, at a tenderness that these stories always seem to have, the personal side that makes them so addictive. So...I think the music matches what the game is supposed to be and thus I am personally fine with it. in fact, I love the new music...
There...my two cents...
