Auto‑roadmap Generator for Devs
A free tool called “Gameplan Turbo” can auto‑generate full game roadmaps from a concept in under 10 minutes using Codex/CC — a shortcut for solo devs who need rapid, structured design documents. (x.com)
The project lives on GitHub under howlshot/gameplan-turbo and describes itself as a planning‑first game development workspace aimed at small teams and solo builders. (github.com) The app structures a project into modules named Concept, Design Pillars, Core Loop, Controls & Feel, Content Bible, Art & Tone, and Technical Design, and includes a Vault for references and a Prompt Lab for model-driven outputs. (github.com) Repository documentation includes a how‑to page titled using-with-codex-for-games.md that instructs creators to fill Concept, Design Pillars, Core Loop, and Controls & Feel before asking Codex to implement features. (github.com) That same guide recommends generating a Full GDD or Mini GDD in Prompt Lab, producing an Agent System Prompt targeting Codex, and creating staged implementation prompts to drive a Build Roadmap rather than attempting all stages at once. (github.com) Gameplan Turbo can be used without an AI provider—its README notes the app is functional offline for planning and that AI is only required for model‑generated outputs; the docs also state the browser app does not store ChatGPT OAuth tokens. (github.com) OpenAI’s Codex tooling (the Codex app and Codex CLI) is documented as a compatible execution target and is included with ChatGPT Plus, Pro, Business and Enterprise tiers, offering a supported route to run the generated stage prompts against code‑writing agents.
