# What does procedurally generated mean in gaming?

> Procedurally generated content is made by algorithms at runtime from rules and random seeds, instead of being hand-built level by level.

Procedurally generated means the game creates content with algorithms instead of designers placing every piece by hand. Developers write rules — how terrain rises, which rooms can connect, what stats a weapon can roll — and the game uses them, often with a random "seed," to build maps, levels, loot or whole planets. The same seed produces the same result, which is how players can share Minecraft worlds.

## How it works

1. **A seed starts the process.** A number feeds a pseudo-random generator, so results look random but are repeatable.
2. **Rules shape the output.** Noise functions such as Perlin noise create natural-looking hills and caves; grammars and templates decide how rooms and corridors connect.
3. **Hand-made pieces are mixed in.** Many games combine designed chunks — rooms, buildings, points of interest — with procedural placement, so the result feels intentional.

## Where you see it

- **Worlds and terrain:** Minecraft, No Man's Sky, Starfield's planet surfaces.
- **Levels and dungeons:** roguelikes such as Rogue, Spelunky and The Binding of Isaac; Diablo's randomized dungeons.
- **Loot:** Diablo and Borderlands roll random stats on weapons and gear.

Not every game with variety is procedural. Competitive maps in League of Legends, Fortnite or Counter-Strike are designed by hand so that matches stay fair and learnable.

## Why developers use it

- **Scale:** a small team can produce a huge world.
- **Replayability:** every run or map is different.
- **Small file size:** the game stores rules, not every level.

The downside is repetition: algorithms can produce content that feels samey or empty unless designers add handcrafted detail.

## FAQ

**Are all the planets random in Starfield?**
Planet surfaces are largely procedurally generated, while cities, quest locations and many points of interest are designed by hand and placed into them.

**Will Starfield really have 1,000 planets?**
Yes, Starfield has over 1,000 planets you can visit, most of them procedurally generated and uninhabited.

**Does Earth exist in Starfield?**
Yes. Earth is in the Sol system, but it is a barren, uninhabitable world in the game's story.

**How big is a Minecraft world?**
The playable area is bounded by a world border about 60 million blocks across, far larger than anyone can explore in practice.

**Is Minecraft made with C++?**
The original Java Edition is written in Java. Bedrock Edition, used on consoles, mobile and Windows, is written in C++.
