Baker-Care Principle)[15] which states "System (including but not limited to 'the rules') is defined as the means by which the group agrees to imagined events during play."
Emily Care Boss discussed Baker's mechanical contributions to role-playing games in her chapter "Key Concepts in Forge Theory" in Playground Worlds: Creating and Evaluating Experiences of Role-Playing Games.
