These materials serve as tools within interactive storytelling experiences, typically involving collaborative narratives and character development. For example, a deck might contain items, abilities, or encounters that players integrate into their character’s actions and decisions during a gaming session. They add a layer of randomization and tactical decision-making to play.
Their significance lies in their ability to streamline gameplay, enhance world-building, and foster creative problem-solving. Historically, such aids have evolved from simple reference sheets to elaborately illustrated components that complement or even replace traditional dice rolls. Their inclusion enriches both the players’ engagement and the game’s dynamic.
