Arkhandus said:Except that those parts of the PHB and DMG are not Open Game Content, so you'd have to include a different set of chargen/XP rules of your own making. For instance, in Monte Cook's Arcana Unearthed/Evolved, the level advancement table has slightly different XP values and such.
Exactly.
The SRD doesn't have everything needed to play. It has almost everything needed. At that point, it becomes a variant, so you have to pick one. If you already HAVE to make a variant, why not go with an established line?
