Imagination, structure, and the right tools to guide the creative process are key components of a successful tabletop roleplaying game. Good quality tabletop RPG books also provide extensive lore, modular mechanics, and creative inspiration, which elevate the gameplay experience above the basics, provide a foundation for creating diverse worlds and cultures, and help create impactful choices that maintain player interest through long-term campaigns. An example of a sourcebook that supports creativity and retains the balance and clarity of the game is OnixShu Fantasy Workshop's collection of sourcebooks. Each book in the OnixShu Fantasy Workshop collection was written to generate ideas while being easily modified for different play styles and settings. The books include clear layouts, logical progression, and immersive themes that allow game masters to prepare for and run dynamic sessions.
