With offices in Seattle, Washington and Coeur d'Alene, Idaho, the company specialized in material for the d20 System.

While initially enthusiastic about 4th edition and the prospect of being able to publish third-party products for that game, in July 2008 company co-founder Clark Peterson declared the third-party license for fourth edition D&D "a total unmitigated failure".

In July 2014 a Kickstarter was launched by Frog God to fund a series of products for the then-upcoming 5th edition of Dungeons & Dragons, under the Necromancer Games label.

[11] Here is an excerpt[12] from an interview done by Role-Play News in 2000 with Clark Peterson and Bill Webb about their view on what is the "First Edition Feel": Clark Peterson: First Edition is the cover of the old DMG (Dungeon Masters Guide) with the City of Brass; it is Judges Guild; it is Type IV demons not Tanaari and Baatezu; it is the Vault of the Drow not Drizzt Do'urden; it is the Tomb of Horrors not the Ruins of Myth Drannor; it is orcs not ogrillons; it is mind flayers not Ilithids (or however they spell it); it is Tolkien, Moorcock, Howard and Leiber, not Eddings, Hickman, Jordan and Salvatore; it is definitely Orcus and the demon-princes and not the Blood War; it is Mordenkainen's Faithful Hound not Elminster's Evasion; and it is Artifacts and Relics from the old DMG (with all the cool descriptions).

I always say we want to be the VW Bug of roleplaying companies, meaning that we want to have a modern style and appeal but an obvious link to the past.

But our modules have the same basic format of the old modules—inset art, module number in the upper left corner, diagonal band in the upper left corner, logo placement, etc.
