I consider this book an invaluable resource for anyone interested in running a hard science fiction campaign (it's an in-system, no faster-than-light travel setting). The material presented is highly detailed and useful, and had a surprising degree of verisimilitude considering the obvious anime influences. That fusion of anime and hard science is probably what appeals to me most because I love the idea of high tech mecha mixed with an appreciation of the danger and physics of space-travel make it a very compelling setting for me and this particular book really brings all that to life.
