How to create with GameGen

Three steps from idea to downloadable asset.

    Choose genre and scope

    Pick fantasy, sci-fi, or another genre, and whether the document covers a region, kingdom, or entire world.

  3. 3

    Select document sections

    Geography, history, factions, legends, quest hooks—mix and match as needed.

Trusted creators

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.

Alex Chen

Solo indie dev

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.

Jordan Park
