1e D&DG = amusing for the inclusion of the Lovecraftian deities. Dunno why Shub-Niggurath was less powerful than Cthulhu, but no big deal. The entire book was so bad and so useless that it was campy and amusing for that fact alone: a classic by virtue of being so kitchy. I treasure my copy
3e D&DG = the crystal pepsi or new coke of D&D books: Ill conceived, poorly designed, left a rancid taste in your mouth that you kept desperately trying to get rid of. Wretched, wretched design, poor implimentation, and utterly and completely useless. A waste of paper and good artwork.
