Structure before AI art
Lock continents and biomes from a seed, then use Game Maps for styled PNG concepts of a chosen region.

Seed → height → climate → biomes in your browser. Save into a World as JSON + PNG — generation uses no AI credits.

Start nowHow to create with GameGen
Three steps from idea to downloadable asset.
- 1
Pick a template
Continents, archipelago, island, pangea, or mediterranean — each runs a height script on a cell graph.
- 2
Set seed and size
Same seed + template reproduces the same world. Larger grids take a bit longer but export more detail.
- 3
Generate
Explore biomes, politics, and layers interactively. Download PNG/JSON, or save into a World to reopen later.

Loved by indie developers
“I shipped my Game Jam entry with AI-generated sprites and BGM from GameGen. Saved me at least two days of asset work.”
“The pixel character and asset pack tools let me test combat feel before hiring an artist. The style was consistent enough for a vertical slice.”
“HD portraits with transparent backgrounds dropped straight into Ren'Py. We iterated on character designs in hours instead of weeks.”
Frequently asked questions
- Is this the same as Game Maps?
- No. World Map Generator builds height/biome/political layout from a seed. Game Maps generates AI top-down concept PNGs for the board. Use World Map for procedural continuity; Game Maps for styled art.
- Does it cost credits?
- Generation runs in your browser at no credit cost. Saving into a World requires login and is temporarily free.
- How does this relate to Azgaar FMG?
- Algorithms and biome colors are inspired by Azgaar's Fantasy Map Generator (MIT). GameGen uses its own PCG and workbench — not an embedded copy of the full FMG app.
