Picked this up at the recommendation of a friend of a friend and have been extremely happy with the purchase. The FATE system is beautifully flexible and the mini-games added in Diaspora really round out the storytelling possibilities.
My original hope was just to find something different from 4e but Diaspora has proven to be much more than that. Hell, the cluster and character creation portions alone are worth the price of admission!
Highly recommended for anyone looking for a relatively free-form system that focuses on storytelling over rules minutiae.
