10. Cellular Automata On of the easiest and most popular ways of generating procedural content. Start with random cells filled in, then apply a sweep of rules to all cells, perhaps multiple times, until an interesting map is generated. Can produce interesting fractal shapes, very useful in making terrain maps, caves, or other naturalistic systems. Ultimately all of reality is made by cellular automata!

11. Cellular automata!

19. Why use PCG? Replayability Save costs Vast content production Can enable new types of gameplay Can surprise the creator!

22. Some further examples Sir, You Are Being Hunted Generally islands based on English countryside and towns Using an array of techniques and tweaks to make believable, “lived-in” environments

23. Some further examples Mushroom-11 You control a group of cells that behave like cellular automata Procedural generation is the game

24. Some further examples No Man’s Sky Procedural worlds, terrain, lifeforms, etc Uses a vast array of techniques Able to make a huge, varied game with a small group of developers in Guildford

25. Some further examples Microsoft Songsmith vs Van Halen Made by Microsoft as a tool to provide a backing track to your own singing. Produces hilarious results when applied to well known songs. Proves the point that bad procedural content is boring! Also, Mozart > Microsoft.
