Game Design Document

This generates full Game Design Documents as formatted .docx and .pdf files, aiming for the 40-80 page range that publishers expect. It walks you through a structured interview (genre, platform, monetization model, comp titles) before writing, then produces sections covering mechanics, progression, UX flows, art direction, economy design, and competitive analysis. The prompt positions itself as a senior designer who's shipped at Riot and Blizzard, and it enforces concrete specifications over vague descriptions. It also outputs pitch decks and one-pagers. Use this when you need to turn a game concept into something a team can build from or a publisher can evaluate, not for brainstorming or answering design questions.
