Procedural generation is a method of creating game content through rules, algorithms, or systems rather than placing every detail by hand. The result can be a map, level, item, world, enemy layout, or event.
Why games use it
Procedural generation can make games feel fresh across many playthroughs. It is common in roguelikes, survival games, sandbox games, and exploration games.
Designed rules still matter
Procedural does not mean random chaos. Developers define rules so the generated content is playable, fair, interesting, and consistent with the game's style.
Good procedural generation combines surprise with structure.
