World generation refers to the process of creating a virtual environment in video games or simulations. This can involve designing landscapes, ecosystems, and structures, often using algorithms to ensure variety and realism. Techniques like procedural generation allow developers to create vast worlds without manually designing every detail. In many games, such as Minecraft or No Man's Sky, world generation plays a crucial role in enhancing player experience. These systems can produce unique terrains, weather patterns, and biomes, making each player's journey distinct. This randomness adds replayability and encourages exploration, as players encounter new challenges and discoveries in their adventures.
