GIving this book a 4/5 only because it is not an absolute must have. It does however add alot of races and can make any racial interactions easier and just by adjusting some stats, talents, or powers you can create any new race or sub species. The fact you can also use the races in any setting or any BASH product is a bonus. A couple of the new powers, advantages presented are naturals for a sci fi setting or even a supers settings. I guess every race could have used an illistration as some names do not directly conjure the right vision. the descriptions do however do a great job. this more of my preference than a slight on the functionality of this book.
