Blue Rose is a fantasy role-playing game published by Green Ronin Publishing in 2005. The game is in the romantic fantasy genre — it is inspired by fantasy fiction such as that of Mercedes Lackey and Diane Duane as opposed to Robert E. Howard–style of swords and sorcery. In romantic fantasy the emphasis is on role-playing and character interaction more than on combat. The game uses a derivative of the D20 system, called True20. Blue Rose won the Gen Con ENWorld Roleplaying Silver Medal for Best Rules in 2005. Green Ronin subsequently released True20 as a separate system without a setting and genre neutral.
