I am a very big fan of all things dragon. Given that, the options presented in this PDF are great, especially the races (love my half-dragons) and the subclasses. The items and spells are also a very nice addition that gives a unique spin on things. Even if most of it is balanced, and seems like its been playtested, some things can be overpowered (on paper at least), but i would say its better if something is OP and then made weaker by simply taking away a thing or two instead of changing the whole template. Ive been following this project for a while, and all I can say is that this is a great set of options, especially if you love dragons.
