Game Mastering is the art of guiding players through a tabletop role-playing game (RPG) like Dungeons & Dragons. The Game Master (GM) creates the story, sets the scene, and controls the non-player characters (NPCs) that the players interact with. They help to immerse players in a fantasy world, making decisions that affect the game's outcome and ensuring everyone has fun. A good GM balances storytelling with gameplay, adapting to players' choices and keeping the adventure engaging. They also manage the rules and mechanics of the game, ensuring that everyone understands how to play. Ultimately, the GM's role is to facilitate a collaborative experience where creativity and imagination thrive.
