The problem I know firsthand. I make games with no team and no budget, and the road from a spark of an idea to a usable Game Design Document, controller code, coherent art, and music takes weeks of fragmented work across half a dozen tools. Tutorials help you learn; nothing assembles the whole pre-production package for you. So I built the tool I needed: an AI pipeline that takes a single sentence and returns a complete, downloadable game starter kit. What it does. Type an idea like "a cozy co-op farming sim on a haunted island", pick an engine and a document format, and launch the pipeline: a GDD agent drafts a structured design doc following Scott Rogers' methodology (one-sheet, ten-pager, beat chart, or full GDD), grounded in real market data from RAWG, IGDB, and Steam. A code agent writes an engine-targeted controller script (Godot, Unity, or Unreal). A visual agent generates sprites, concept art, and UI concepts in a consistent style, with one-click SAM background removal. A review agent then audits the GDD against a professional checklist and applies only the fixes you confirm — nothing changes without your approval. Finally, a music agent composes original loops you can preview and download. Everything exports in one click: Markdown, JSON, TXT, styled Pro/Gamebook PDFs, PNGs, WAVs. Key features: • End-to-end multi-agent pipeline: GDD → code → art → review → music • Rogers-method authoring form (3Cs, core loop, features, AI, physics) • Self-correcting review loop with confirm-to-fix and diff inspection • Market-grounded generation (RAWG, IGDB, Steam signals in every doc) • Transparent per-call cost tracking + bring-your-own-key for all APIs • 5 languages (EN/FR/ES/DE/IT), voice dictation, local history, demo mode that works with zero API keys Built with. Next.js 16 + FastAPI, powered by the Meta Model API — Llama for reasoning, Muse Image for visuals, SAM for cutouts — plus Replicate MusicGen, RAWG, IGDB, and Steam data. Try it. Live demo: https://multimodal-game-architect-xi.vercel.app (open source, evaluated version: tag demo-v3). Note: the free-tier API cold-starts for 1–2 min after idle — retry once if the first call fails. What's next? Playable-prototype export (Godot scene scaffolding), multiplayer balancing passes, and community template sharing. Overall improvements for generated GDDs.
