"Just One More Thing": My Prototype's Scope Creep Autopsy
"Just One More Thing": My Prototype’s Scope Creep Autopsy
Prototypes are supposed to be fast, focused, and disposable. Mine wasn’t. It ballooned into a Frankenstein’s monster of half-baked features, dragging development time and killing any chance of a quick greenlight. I’m going to share exactly how I screwed up, so you don’t make the same mistakes.
The Allure of “Just One More Thing”
It always starts innocently, doesn’t it? “It would be really cool if…” That’s the siren song of scope creep. For my project, a top-down roguelite shooter, it began with a simple idea: “It would be really cool if the player could dash.”
Seemed harmless. A quick movement ability to make the game feel more dynamic. Implementing it wasn’t the problem. The problem was what came after.
The Domino Effect
The dash changed everything. Level design needed tweaking to accommodate the new mobility. Enemy AI now had to anticipate and react to dashes. Suddenly, I needed to add visual effects to make the dash feel impactful. Then came the upgrade system - dash distance, cooldown reduction, even elemental damage on dash.
What started as a simple movement tweak cascaded into a series of interconnected features, each one requiring more work than the last.
Feature Fever
I started chasing shiny objects. “Procedural weapon generation would be amazing!” I thought. Ignoring the fact that the core gameplay loop wasn’t even solid, I dove headfirst into complex algorithms for weapon stats, prefixes, and visual variations.
Hours were spent on weapon systems that didn’t address the fundamental question: Is the game fun? The answer, obscured by piles of unfinished features, was a resounding “Maybe, if I ever get around to polishing the actual gameplay.”
The “Polish” Paradox
I told myself that “polish” was the key. More particles, more animations, better sound effects. I thought these would magically transform the game from a rough prototype into a polished demo.
I was wrong. Polish is essential, but only after the core mechanics are nailed down. Trying to polish a fundamentally flawed game is like putting lipstick on a pig.
Ignoring the Initial Goal
The biggest mistake? I forgot the original goal of the prototype. It wasn’t to create a fully featured game. It was to answer one simple question: Is the core gameplay loop engaging?
I became so obsessed with adding features that I lost sight of the initial objective. I was building a house without a foundation.
Project Management (or Lack Thereof)
My project management was non-existent. No roadmap, no clear milestones, no system for prioritizing tasks. I was just coding whatever seemed interesting at the moment.
This is a recipe for disaster. A well-defined roadmap helps keep you focused on the essential features. Prioritization prevents you from wasting time on non-essential tasks.
The Autopsy: Lessons Learned
So, how do you avoid this trap?
Define the Core Loop: Before writing a single line of code, clearly define the core gameplay loop. What’s the fundamental action the player will be performing repeatedly? Is it fun? The prototype should focus solely on answering that question.
Set a Hard Feature Limit: Decide on the absolute minimum number of features needed to test the core loop. Stick to that limit. No exceptions.
Timeboxing: Allocate a specific amount of time for the prototype. When the time is up, stop working on it. Evaluate what you have. Don’t fall into the trap of endlessly tweaking and adding features.
Prioritize Ruthlessly: Use a simple prioritization system like MoSCoW (Must have, Should have, Could have, Won’t have). Be honest with yourself about what’s truly essential.
Regular Playtesting: Get feedback early and often. Don’t wait until the prototype is “perfect” (it never will be). External feedback can help you identify flaws in the core loop and prevent you from wasting time on unnecessary features.
Document Everything: Keep a detailed record of your design decisions, goals, and progress. This will help you stay on track and avoid scope creep.
Kill Your Darlings: Be prepared to cut features that aren’t working, even if you spent a lot of time on them. It’s better to have a small, polished prototype that demonstrates a fun core loop than a bloated, unfinished mess.
The Next Prototype
My next prototype will be different. It will be lean, focused, and ruthlessly prioritized. I’ll define the core loop, set a hard feature limit, and stick to a strict timeline.
I’ve learned my lesson. “Just one more thing” is a dangerous mantra. It’s a shortcut to scope creep, feature bloat, and ultimately, a failed prototype.
Don’t let it happen to you.
