Sandbox Generator - a tool worth it's weight in gold (review) (solo RPG)

Daniel (@dungeondive) reviews Atelier Clandestine’s Sandbox Generator and frames it as one of the most inspiring tools of its kind he has used — to the point he is hand-keying a series of 19-hex tiles for Dungeon Knights patrons off the back of it. The book works in 19-hex regions that you build outward in a spiral from a starting settlement, with biomes (grasslands, forest, hills, marsh, mountains), faction control as a separate layer, and contested hexes used as ready-made adventure seeds.

The detail is the selling point. Landmark tables run to 36 entries per category — natural, artificial, magical — plus hazards and “empty” hexes that still yield rumours, ecology clues, or alchemy recipes. Settlements scale from hamlets through villages, cities, castles, towers, and abbeys, each with appropriate sub-tables. The dungeon section allows up to six dungeons per 19-hex tile, any of which can interconnect underground into a mega-dungeon. Random generators cover coats of arms, criminal organisations, taverns (including signage), wizards, NPCs, and a small Adventures at Sea coda.

Daniel’s house tweaks: six-mile hexes instead of two-mile, and a one-in-six chance of biome “slippage” toward jungle, desert, or wasteland after two of the same biome in a row.


Sandbox Generator goes deep on coats of arms and tavern signage — useful colour, or detail you’ll never reach for in actual play?
