Narrative pre-production
Use GameGen to draft geography, history, factions, and quest hooks as Markdown — then fold the stronger sections into your GDD without writing blank-page lore for days.
Open-world and RPG projects stall when lore is either missing or scattered across chat threads. GameGen's World Building generator drafts structured Markdown covering geography, history, factions, legends, and quest hooks from a theme you control.
This guide shows how to treat AI output as a first-pass GDD appendix: generate modules, cut contradictions, and link surviving facts to systems (factions → quests → maps) instead of pasting an unread novel into your repo.
Follow these steps in order for a citable, repeatable workflow.
Write 3–5 bullets: genre (fantasy, sci-fi), player fantasy, tone (grim, whimsical), and non-negotiables ("no guns", "five-day festival setting"). Constraints keep the AI from inventing competing cosmologies.
Run World Building with the modules you need now — geography and factions often unlock design sooner than deep legends. Export Markdown so it lives next to your GDD in version control.
For each faction or region, add one sentence of gameplay effect ("controls iron supply → rare weapon vendors"). Delete purple prose that never touches quests, economy, or level themes.
Promote surviving place names into Game Map prompts and NPC beats into dialogue or quest lists. Re-generate only modules that contradict your locked rules.
Put in the GDD: player fantasy, core loop, resource constraints, faction goals that affect quests, and region list tied to levels. Keep long legends in a lore appendix unless they change systems.
AI world docs are excellent for naming density and first-pass relationships. They are weak at balance — numbers for XP, gold, and combat still need a designer, not a lore paragraph.
World Building → Markdown backbone. Game Maps → visual references for regions you kept. Game Dialogue → NPC lines that reference faction names you locked. Pixel/HD characters → portraits for key NPCs once roles are stable.
