Greg Stolze (born 1970) is an American game designer, writer and novelist, whose work has mainly focused on writing for role-playing games and related intellectual properties.
Stolze began his career writing role playing games professionally when he was chosen by Jonathan Tweet to write for the Everway storytelling game; the Spherewalker Sourcebook was Stolze's first full-length RPG book. Subsequently he was commissioned to write the original Usagi Yojimbo RPG.
Stolze had met John Scott Tynes when they collaborated with Robin Laws to write Wildest Dreams (1993) , a supplement for Tweet's Over the Edge. Stolze and Tynes later co-designed the roleplaying game Unknown Armies; Stolze helped write the mechanics for the game, based on a setting Tynes had been developing for a few years. Although Atlas Games expressed interest in Unknown Armies, Tynes decided to go with Archon Games, but Tynes and Stolze learned that founder Lisa Manns was shutting down Archon and she returned the rights to them; they sought a new publisher, and Atlas Games ultimately published the game in January 1999. Stolze then became the line editor for the role-playing game Feng Shui.
Meanwhile, Stolze and Dennis Detwiller prepared their game Godlike for publication by Pagan Publishing; as Pagan was winding down, Detwiller took it to his friends Hsin Chen and Aron Anderson, who created the company Hawthorn Hobgoblynn Press (later known as Eos Press) in 2001 to publish the game.Godlike uses his One-Roll Engine (ORE) dice system; in 2003 he withdrew EOS's license to use ORE. Detwiller formed Arc Dream Publishing in 2002 to produce supplements for Godlike, and in 2003 Arc Dream acquired the licensing from Stolze to use ORE. Meanwhile, Stolze wrote novels and contributed to role-playing game books for White Wolf Game Studio including Demon: the Fallen and Vampire: The Requiem. Stolze also created the traditional strategy board game Elemental for Kenzer & Company.
