When to Use Game Design Docs Instead of Winging It

Posted by Gemma Ellison

The allure of indie game development often lies in its freedom. The ability to follow your muse, code on a whim, and “wing it” until a playable prototype emerges is powerful. But this freedom can quickly turn into a tangled mess of unfinished features, scope creep, and a general sense of being lost. So, when do you ditch the free-flowing approach and embrace the structure of a Game Design Document (GDD)?

The Pitfalls of Pure Improvisation

Let’s be honest, diving headfirst into coding without a clear plan feels amazing at first. You’re building, creating, and seeing immediate results. The problem? You’re likely building without a foundation. This leads to:

Losing Direction: The initial spark fades, and you’re left wondering what the core gameplay loop even is.
Scope Creep: “Just one more feature…” becomes the mantra, ballooning your project into an unmanageable beast.
Miscommunication (Even Solo!): You forget your initial design intentions, leading to internal debates and wasted effort.

These aren’t theoretical problems. They’re the silent killers of countless indie projects. Remember that awesome platformer you started last year? Yeah, scope creep probably got to it.

When to Embrace the GDD

A GDD doesn’t have to be a massive, intimidating document. Even a lightweight GDD can provide crucial structure. Here’s when you should consider creating one:

Beyond the Prototype: If your prototype shows promise and you plan to develop a full game, a GDD is essential.
Team Collaboration: If you’re working with anyone else, a GDD ensures everyone is on the same page. No more interpreting your cryptic coding style.
Complex Systems: Games with intricate mechanics, branching narratives, or extensive worldbuilding benefit greatly from documented systems.
You’re Feeling Lost: If you’re consistently questioning your design decisions or struggling to prioritize tasks, a GDD can bring clarity.

A GDD acts as a North Star, guiding you through the often-turbulent waters of game development. It helps you stay focused on your core vision and avoid unnecessary detours.

Lightweight GDD: A Practical Approach

The key for solo devs is often a lightweight GDD. This isn’t about writing a novel; it’s about outlining key elements:

Genre and Target Audience: Who are you making this game for?
Core Gameplay Loop: What do players do repeatedly and enjoy?
Key Features: The essential elements that make your game unique.
Art Style and Tone: What visual and emotional experience are you aiming for?
Basic Story Outline: (If applicable) The main plot points and character arcs.

Don’t be afraid to iterate on your GDD as you develop. It’s a living document, not a stone tablet.

Real-World Examples of GDD Success

Many successful indie devs swear by GDDs, even for small projects. Consider these examples:

Stardew Valley: While initially developed solo, Eric Barone (ConcernedApe) undoubtedly had a clear vision documented somewhere, guiding the game’s expansive features and consistent tone.
Undertale: Toby Fox’s RPG likely benefited from a detailed plan for its narrative, characters, and battle system, contributing to its cohesive and impactful story.

These games weren’t built on pure luck. They were built on a solid design foundation.

The Power of Documentation, Even When Winging It

Here’s the secret: even when you’re “winging it,” documentation is your friend. Track your design decisions, inspirations, and experiments. This isn’t about rigid planning; it’s about capturing your creative process.

Why? Because you will forget. You’ll have brilliant ideas that vanish into the ether. You’ll make design choices and later wonder, “Why did I do that?”

This is where a game dev journal comes in.

Track Game Development Progress with a Game Dev Journal

A game dev journal is your personal record of your game’s evolution. It’s a space to:

Note down ideas and inspirations
Document design decisions and the reasoning behind them
Track progress on tasks and milestones
Reflect on challenges and solutions
Log bugs and fixes

Think of it as a developer’s diary, but instead of documenting your feelings you document your game’s progress.

Staying Consistent with Devlogs

Consider turning your game dev journal into a public devlog. Sharing your progress online not only keeps you accountable but also builds hype and gathers valuable feedback from potential players.

This doesn’t mean revealing all your secrets. Focus on sharing interesting challenges, design insights, and progress updates.

Organizing Your Creative Process

The key to a useful game dev journal is organization. Here are some tips:

Date Each Entry: Essential for tracking the evolution of your design.
Use Headings and Subheadings: Make it easy to find specific information.
Include Screenshots and Videos: Visual aids are incredibly helpful.
Be Honest and Reflective: Don’t be afraid to admit mistakes or share doubts.

A well-organized journal becomes an invaluable resource, allowing you to revisit past decisions, learn from your mistakes, and stay inspired.

Avoid These Common Pitfalls

Perfectionism: Don’t get bogged down in making your journal “perfect.” Just write.
Inconsistency: Aim for regular updates, even if they’re brief.
Ignoring Your Journal: Regularly review your entries to identify patterns and insights.

Treat your game dev journal as a living document that evolves alongside your game.

So, ditch the chaos and embrace the power of documentation. Your game will thank you for it. By consistently using a game dev journal, or game development log, you will be able to better track game development progress, while also organizing your creative process!
