Procedural Generation

Instead of authoring every result by hand, procedural generation produces content from algorithms, rules, parameters, and random or fixed seeds. Games use it for terrain, levels, item statistics, vegetation, quests, animations, and countless variations. The same seed can often reproduce the same output, which helps sharing and debugging. Procedural does not mean completely random: designers define constraints, combine authored pieces, test edge cases, and curate results. It can expand variety and reduce manual work, but repetition, impossible layouts, and weak pacing appear when the generator lacks strong rules.
