What is a PCG?

PCGs, or Procedural Content Generators, are tools or algorithms used in game development and other fields to automatically create large amounts of content, such as levels, maps, or textures, through procedural methods rather than manual design. This approach allows developers to produce diverse and complex environments efficiently, often resulting in unique experiences for each user. PCG is widely used in video games for generating random terrain, dungeons, or even storylines, saving time and resources while adding replayability. The techniques can range from simple rule-based systems to advanced algorithms involving artificial intelligence.
