Definitely amazing. This sounds like something you would be swept away by on a surround sound. Plus, the wide range of instruments keeps it from getting boring. Definitely a 10. Plus, for game themes..... Hmmm... I'm thinking Soul Calibur. I could totally hear this in it.
The ONLY thing I have to point out, is that the end/begining of the loop when it replays is a tad rough. But then again, that could just be my computer, or if it IS the song, hey, a tiny clip can fix it. I love this song. Definitely a favorite. 3 thumbs up.
