About this service
We write a game design document from your concept: the core loop, controls, mechanics, levels or missions, progression, the in-game economy and monetisation. It is written so programmers, artists and level designers each find what they need, with numbers where balance matters. Works for mobile, PC and indie projects from hyper-casual to RPG.
What is included
- What you getA game design document with concept, core loop, mechanics, controls, level outlines, progression and, from Standard, economy and balance tables. It comes as formatted text you can paste into a document or send to developers; any time or cost figures are rough guidance, not a quote.
- Core loopWhat the player does every minute
- Mechanics and controlsRules, inputs and feedback
- Levels or missionsGoals, obstacles and difficulty curve
- Progression and economyFrom Standard: currencies, rewards and costs

Questions and answers
Do you write the story and dialogue?
The GDD covers story at concept level. Full narrative and dialogue are a separate game writing service.
Are balance numbers final?
No. They are a starting point to test in playtests and tune.
Can it help pitch to a publisher?
Yes, the one-page concept works as a pitch summary; the decision is the publisher's.
