When you develop a video game it is very easy to get excited about an idea and want to start programming immediately. However, skipping documentation (which in the world of video game development is known as "Game Design Document" or "GDD") can lead to serious problems: inconsistent mechanics, drastic changes in development, lack of direction and, in the worst case, an abandoned project (a very common evil among video game developers :s).
Why document your idea?
Before writing a single line of code, you need to have a clear vision of what you want to create. Documenting your game idea will help you to:
- Define the central concept: What is the game about?
- Establish the key mechanics: How to play? What are the rules?
- Organize development: A well-structured document facilitates planning, assignment of tasks and control over development progress.
- Avoid unnecessary deviations: With a clear guide, it will be easier to stay true to the initial vision of the game.
What should the initial documentation (GDD) include?
You don't need a 100-page document, but you do need a solid outline to serve as a base. Here are the key elements:
1. General summary
A brief description of the game. What makes it special? What genre does it belong to? What is your main objective?
2. Game mechanics
Explains how the gameplay works. Includes controls, player interaction, progression and main challenges.
3. Story
If your game has a narrative, outline the story, world, and main characters.
4. Visual and sound style
Describe the art direction and type of music/sounds that will accompany the experience (What should the game look like and sound like?).
5. Platform and technology
Define in which platforms it will be released on (PC, console, mobile) and what tools or engines you will use (Unity, Unreal, Godot, etc.).
6. Target audience
Who is your game designed for? Casual or hardcore gamers? Children or adults? (or older adults, why not?)
7. Initial Roadmap
Outlines a roadmap with major development milestones. This will help you maintain progress and avoid blockades.
Conclusion
Documenting your game idea (creating a GDD) before starting is not a waste of time, but an investment that will facilitate each phase of development. It doesn't mean you have to follow the plan to the letter, but having a solid foundation will save you a lot of headaches. Before opening your game engine, open a document and write down your vision. Your future self will thank you 🙂
