A "game world" refers to the virtual environment where a video game takes place. It includes various elements such as landscapes, buildings, and characters that players can interact with. Game worlds can be open, allowing players to explore freely, or structured with specific paths and objectives. These worlds are designed to create immersive experiences, often featuring detailed graphics and sound effects. They can be based on real locations or entirely fictional settings, like those found in fantasy or sci-fi genres. Players navigate these worlds to complete missions, solve puzzles, or engage in combat with non-player characters (NPCs).
