Game Design Docs vs. Design Journal: Key Differences Explained

Game Design Docs vs. Design Journal: Which is Right for Your Indie Game?

Navigating the world of game development as an indie dev means making a million tiny decisions. Should you use Unity or Godot? Pixel art or vector graphics? And, crucially, how should you document your game’s design? The classic Game Design Document (GDD) looms large, but is it always the best approach? Or would a more flexible Design Journal serve you better?

I recently sat down with Sarah, a solo indie developer working on a narrative puzzle game called “Echo Bloom,” to explore this very question.

“Early on, I thought I had to have a massive GDD,” Sarah confessed. “Every mechanic, every character backstory, every single puzzle solution meticulously planned out. It was… suffocating. I spent more time writing about the game than actually making it.”

That’s a common pain point. A GDD, in its traditional form, is meant to be a comprehensive blueprint. It’s great for large teams needing shared understanding, but can quickly become an albatross for a solo dev or small team where agility is key.

So, what’s the alternative?

The Allure of the Design Journal

“I scrapped the GDD and started a design journal,” Sarah explained. “Suddenly, things felt freer. I could jot down ideas as they came, experiment without feeling like I was breaking some sacred document, and generally keep a running record of my thought process.”

A design journal is exactly what it sounds like: a living document where you track your design decisions, inspirations, and iterations. Think of it as a developer’s diary for your game. It prioritizes flexibility and personal reflection over rigid documentation.

But, there’s a catch.

“The problem,” Sarah admitted, “was that things got too loose. After a few months, I had a massive, disorganized mess of notes. I started to lose sight of the core vision. Was ‘Echo Bloom’ a dark fairytale or a lighthearted adventure? I couldn’t remember!”

This highlights the inherent risk of relying solely on a design journal: losing focus. Without some structure, it can easily devolve into a stream-of-consciousness dump, making it hard to find specific information or remember why you made certain choices.

Striking the Balance: A Hybrid Approach

The key, it seems, isn’t choosing one over the other, but finding a balance. “I ended up creating a 'living GDD’,” Sarah said. “It’s still a document, but it’s structured more like a wiki or a collection of interconnected notes. I have a core ‘pillar document’ that outlines the main themes, gameplay loop, and target audience. Then, I have separate sections for specific systems, characters, and levels, all linked together.”

This approach allows for the benefits of both: the structure and clarity of a GDD, combined with the flexibility and iterative nature of a design journal.

Here are some actionable tips for structuring both:

• GDD Pillar Document: Keep this concise (2-3 pages max). Focus on the core vision, target audience, genre, key mechanics, and unique selling points. This is your North Star.
• Modular Sections: Break down the GDD into smaller, manageable sections. Character bios, level designs, AI behavior – each gets its own space.
• Design Journal Entries: Date each entry and clearly label the topic. Summarize your thoughts, experiments, and decisions. Link these entries back to relevant sections in your GDD.
• Regular Review: Schedule time each week to review your journal entries and update the GDD accordingly. This ensures your documentation stays current and reflects your evolving vision.
• Embrace Iteration: Don’t be afraid to change your mind! The goal is to capture your thought process, not to create a perfect, unchangeable document.

Avoiding Common Pitfalls

Sarah shared a few hard-earned lessons:

• Don’t over-detail upfront: “Resist the urge to plan everything out before you’ve even prototyped anything. Focus on the core mechanics first.”
• Use visuals: “Screenshots, sketches, mood boards – they’re worth a thousand words. Include them in both your GDD and journal.”
• Document why, not just what: “Explain the reasoning behind your decisions. This will be invaluable later when you’re trying to remember why you chose one approach over another.”
• Don’t treat the GDD as a prison: “It’s a guide, not a set of commandments. Be willing to deviate from the plan if a better idea emerges.”

Ultimately, choosing between a GDD and a design journal is about finding what works best for you and your game. There’s no one-size-fits-all answer. The most important thing is to have a system in place for tracking your ideas, decisions, and progress. This allows you to iterate effectively and stay focused on the bigger picture.

Speaking of tracking ideas and decisions, it can be difficult to find the right tools to support your development process. Many developers end up stitching together several different tools, and end up spending more time managing their management tools than actually doing game dev. To help with this, we’ve created a tool to help track ideas and changes during development. It’s designed to be flexible and intuitive, allowing you to easily log your progress and keep your game on track.
