When to Use Prototypes Instead of 'Refactor Later'

Stop Chasing the “Refactor Later” Unicorn in Game Dev

Indie developers are often told that monetization doesn’t matter until the game is “fun.” This is a dangerous myth. Similarly, the idea that you can always “refactor later” in game development, especially during prototyping, can kill your project faster than accruing technical debt.

This isn’t about advocating for waterfall development. It’s about recognizing when a little up-front planning prevents a prototype from collapsing under its own weight. Let’s explore why “refactor later” can be a trap and when you should consider a more structured approach.

The Prototype Death Spiral

The allure of “refactor later” is strong. You want to get something playable now. You tell yourself you’ll clean it up once you know the core mechanic is fun.

But what happens? You hack together features, spaghetti code grows, and dependencies become a tangled mess. Changing one thing breaks five others. The prototype becomes brittle and terrifying to touch.

This isn’t theoretical. I’ve seen countless promising prototypes die this way. The initial excitement fades as the codebase becomes unmanageable, and the developer, understandably, loses motivation. They end up scrapping everything and starting over, or worse, abandoning the project entirely.

Lessons Learned from Veteran Indie Developers

I spoke with several veteran indie developers about their experiences with prototyping and refactoring. The consensus was clear: strategic planning is crucial.

• "Know Your Core": One developer, who’s shipped multiple successful titles, emphasized identifying the absolute core mechanic you’re trying to prove. If it involves complex interactions, you might need a more robust foundation from the start.
• "Scope Creep is the Enemy": Another developer shared a story of adding “just one more feature” to a prototype, leading to a refactoring nightmare. They now ruthlessly cut scope and focus on the essential elements.
• "Document, Document, Document": A common theme was the importance of documentation, even for prototypes. Simple notes about the architecture, dependencies, and known limitations can save hours of debugging later.

When to Plan (Instead of Just Hacking)

So, how do you decide when to invest in a more structured approach for your prototype? Here are some indicators:

• Complex Mechanics: If your core mechanic involves intricate systems, AI, physics, or networking, a robust foundation is essential. Trying to bolt these things on later is a recipe for disaster.
• Team Collaboration: Even if it’s just you, imagine explaining the prototype to someone else. If you can’t articulate the architecture clearly, it’s a sign you need to plan more.
• Potential for Reuse: Are you experimenting with a system that could be reused in other projects? Investing in a cleaner implementation now can save you time in the long run.
• Refactoring Costs Outweigh Initial Effort: Estimate the time it would take to refactor a messy prototype versus building a more structured prototype from the start. Be honest with yourself.

Actionable Steps for Minimizing Refactoring

Here’s a practical approach to planning and scoping your prototypes:

1. Define the Core: Clearly articulate the core mechanic you’re trying to validate. What’s the smallest, most essential experience?
2. Sketch the Architecture: Before writing any code, sketch a high-level architecture diagram. Identify the key components and their interactions.
3. Document Assumptions: Write down any assumptions you’re making about the game’s design or technology. These assumptions can be valuable later when you’re debugging or refactoring.
4. Embrace Iteration: Plan for multiple iterations of the prototype. Each iteration should focus on validating a specific aspect of the game.
5. Track Progress: Keep a development log to track your progress, decisions, and challenges. This will help you learn from your mistakes and improve your decision-making process.

Track Your Game Development Progress

The best way to avoid the “refactor later” trap is to learn from each iteration of your prototypes. Keeping a game dev journal allows you to track your progress, document your decisions, and reflect on the challenges you face. This allows you to make informed choices, spot problematic patterns, and improve your planning skills.

Using a journal can prevent you from repeating mistakes, making each prototype more focused and efficient. This ultimately saves you time and prevents the dreaded prototype death spiral.
