As a musician, I was disappointed with this one. I could do better in a couple of hours with Cakewalk and my own keyboard. The off-rhythm elements seem random and haphazard. It really doesn't inspire me at all except maybe to take a nap. I would purchase the D&D soundtrack or download the Diablo 2 soundtrack for free before purchasing more of this line.
People into ultra-ambient tracks might like it - as long as you're not actually listening to the music at all.
