I'm the kind of player that opts for every optional customization for race or class, and I am still frequently disappointed in how many limits there are for which race is best paired with a class. This supplement will go a long way for satisfying my urge to build a unique and interesting character that isn't shackled by unnecessary restrictions. I am also a permissive DM, and don't think games are made more fun by imposing limits (insert "Defying Gravity" music here for added effect), so take my feedback with a grain of salt I suppose. I think the writers were thoughtful in their creation and put out a solid piece of work. The result is a well-formatted product ready for GM or Player to use. I'm a fan of Drop Dead Studios and their other Spheres works, and would encourage you to check out their other products and related works created by other third-party publishers.
