The "Fate System" is a framework used in various role-playing games and storytelling formats, particularly in the Fate RPG. It emphasizes narrative-driven gameplay, allowing players to shape the story through their characters' actions and decisions. The system uses aspects, which are descriptive phrases that define a character's traits, strengths, and weaknesses, influencing gameplay and interactions. In the Fate System, players utilize Fate Points to invoke aspects, gain advantages, or reroll dice. This mechanic encourages creativity and collaboration, as players can work together to create compelling narratives. The system is designed to be flexible, adapting to different genres and settings, making it popular among diverse gaming communities.
