I had never heard of this game before, but I picked it up on a recommendation from a friend and I absolutely love it. It's incredibly thematic and seems basically mechanically sound to me - there's a degree of system mastery involved, but it doesn't seem very hard for me to wrap my head around. If you like the sound of the setting / ideas involved, and you don't mind anime themes being involved, I would heartily recommend this.
The clean pdf looks good, and while I have some editing issues with it (mostly typos, no page xx that I've seen), it's nothing too big to overlook. Great game, and I really hope they decide to bring over some of the settings.
