Erick Wujcik offered to design an Amber role-playing game for West End Games, who agreed to look at his work. Wujcik intended to integrate the feel of the "Amber" setting from the novels into a role-playing game, and playtested his system for a few months at the Michigan Gaming Center where he decided to try it out as a diceless game. West End was not interested in a diceless role-playing game, so Wujcik acquired the RPG rights to "Amber" and took the game to R. Talsorian Games, until he withdrew over creative differences. Wujcik then founded Phage Press, and published "Amber Diceless Role-playing" in 1991.
