As a longtime Hero System fan, I may be branded as biased.
However, I do feel that this is a great, concise presentation of the 6th Edition of the Hero System for the superhero genre. It is written clearly, organized logically, and laid out cleanly. All this is tackled in a number of pages that -- for those who may be familiar with the ever expanding pagecount of the Hero System books -- is shockingly short.
It doesn't feel like I was shortchanged, however. The book feels just the right length and provides enough rules, explanations, and examples to allow a GM and set of Players to get started right away!
