 Kuntz was TSR's sixth employee and was initially hired to do shipping; because of the small size of the company, everyone got to do some design work, including the "Greyhawk" supplement (1975).Kuntz also co-authored "Gods, Demi-Gods & Heroes" (1976) with James M. Ward.That same year Kuntz, along with Gygax and Brad Stock, redeveloped Fritz Leiber and Harry Fischer’s personal wargame "Lankhmar" for publication by TSR.
