Greyhawk was a bit of staple D&D, but the thing about it was that it had a more believable setting than the cookie-cutter world of Faerun (Forgotten Realms). A lot of FR is the same as everything else, except with some exotic and esoteric changes. Most of what BioMorons have done is in the already overused Waterdeep and Sword Coast area, and let's not forget the fanwhoring for Asswind Dale.
