Non-Player Characters, or NPCs, are characters in video games that are not controlled by players. Instead, they are programmed by the game developers to interact with players, provide quests, or enhance the storyline. NPCs can vary in complexity, from simple shopkeepers to intricate characters with their own backstories and motivations. In many games, NPCs serve essential roles, such as guiding players through the game world or offering valuable information. They can also populate the environment, making it feel more alive and immersive. Overall, NPCs contribute significantly to the gaming experience by adding depth and context to the gameplay.
