 Ken Rolston reviewed "Castle Greyhawk" for "Dragon" magazine No.135 (July 1988), and described it as a light-hearted treasure "for gamers with a sense of humor".Rolston felt that publishing an anthology of "really low fantasy" scenarios dignified the style of play involving "this sort of bizarre, humorous, incoherent fantasy arcade adventure, where DMs took the totally illogical premises of the D&D and AD&D games, accepted them without question, then improvised thinly rationalized dungeon universes for us to wander about in, smashing and roasting things and having a thumping good time".
