While perhaps in the grand scheme of the Superman mythos these villains are of minor importance, in a roleplaying campaign they are infinitely more useable than the Ubervillains detailed in this book. Another useful chapter deals with designing devices, ranging from Steels battlesuit to Superboy's powerglasses. The system is detailed, flexible, and makes infinite sense. Best of all, it's fun and easy, adding a whole new level to character development or campaign play. Included are several examples, such as the Kryptonian Battlesuit and Conduit's armour.
Some useful advice is lent in the chapter on created super-heroic cities.
The authors have kindly provided a scenario, a trend in DCU sourcebooks that I am most grateful for. Unfortunetaly, the 10 page adventure is somewhat disapointing, which is not surprising since they chose to use Mxyzptlk as the antagonist. A weakness of the villain is his inherant silliness, despite the power he wields. It comes across as a wasted opportunity to either do something interesting with Mxyptlk or, far better, treat us to an advanture featuring one of Supermans more awe-inspiring villains. It would be remise of me if I did not make note of the continued high caliber of production value that D6Legend invests in it's books.
