Procedural Content Generation (PCG) is a method used in video games and other digital media to create content algorithmically rather than manually. This technique allows developers to generate levels, landscapes, characters, and other elements dynamically, often resulting in unique experiences for players each time they engage with the game. PCG can enhance replayability and reduce development time, as it automates the creation of vast amounts of content. Popular examples of PCG can be found in games like Minecraft and No Man's Sky, where the environments and challenges are generated on-the-fly, providing endless exploration opportunities.
