Avoid bad games by prototyping the right way

Main summary

Key takeaways

Gaming

Game storyline / theme

  • The video isn’t about a single in-game story—it’s about the development process: how to avoid wasting months by prototyping the “right way.”
  • Core message: prototypes should quickly determine whether a game is worth pursuing (fun, marketable, technically feasible), instead of evolving into unfinished “mini versions” that delay real development.

Gameplay loop focus (what prototypes are meant to test)

Prototyping is framed as validating fundamentals early:

  • Core gameplay loop: Is the repeated action/interaction (combat, building, etc.) actually enjoyable?
  • Extendability: Early hype (e.g., in the first 10 minutes) doesn’t guarantee the loop works for hours—so the prototype should hint whether it can sustain as a full game.
  • Replayability of the prototype: Even short prototypes (5–10 minutes) should be playable repeatedly, creating that “one more round” feeling and generating new ideas while playing.

Gameplay / production strategies & key tips (practical highlights)

The “3 categories” of prototypes (often combined)

  • Fun prototype

    • Build a very simple version to test whether the core loop is enjoyable.
    • Learn early if mechanics feel bad, rather than after months of development.

  • Marketability prototype

    • Test whether the game can attract people visually.
    • Validate using short (≈15 seconds) functional trailer-style content, since a well-designed game still won’t “sell itself.”

  • Technical prototype

    • Focus on systems risk and technical unknowns—especially for automation/strategy games.
    • Build a deliberately “worst possible” version to surface roadblocks early (e.g., inventory design, interactions between systems) before doing production-quality work.

Dangers / failure modes to avoid

  • Prototype creep via time + side features

    • Risk: getting emotionally attached (naming it, mocking art, adding “just one more feature”), which prevents real loop validation.
    • Result: you keep piling on mechanics too early and never truly test the core.

  • Prototype fatigue

    • If you prototype too long or too frequently (even 1–3 days each), you can produce many prototypes quickly and get demotivated.
    • Leads to “local maximum” thinking—settling for a mediocre prototype (e.g., “6/10”) because you’re tired, even if a better one might come later.

  • Prototypes aren’t guaranteed success

    • A concept that’s fun in a short prototype can collapse when extended (e.g., hype fades after 30 minutes).

Daily execution rule (“kill it if it isn’t proving itself”)

  • Each day of prototyping, the prototype must earn its continued existence.
  • At the end of the day (example: after ~4 hours), ask:
    • Is there enough progress?
    • Is it still on the right track?
    • Would an additional day be worth it?
  • If the answer is “no,” stop immediately and move on—ideas are plentiful.

“Timeboxing” expectation

  • Many prototypes don’t go past 2 days for the speaker’s team.
  • If something survives longer (e.g., becomes a prototype baseline for Kyoto Anomaly), it’s because the vision and mechanics look doable and still fun.

Quality boosters early: visuals + music + ambient sound

Implement “feel” elements from day one to raise prototype value:

  • Music / ambient audio: quickly changes perceived quality and vibe.

  • Visual style (even if rough): style choices strongly affect player interpretation

    • Example: stylized vs. realistic forest can shift tone from cozy to horror.

  • The speaker’s claim: simple audio/visual polish can raise a prototype from roughly 3/10 to 5/10.

After a prototype “works”: throw away old code

  • Once you’ve validated a prototype, don’t continue directly on prototype code.
  • Instead:
    • Keep only a reference build for “what was the vision?”
    • Start fresh for production to move fast and avoid overengineering early architecture.

When is a prototype “good enough” to justify moving on?

A prototype should meet multiple “go/no-go” signals:

  • Clear explanation of the game
    • You can describe it clearly (e.g., “an action RPG where you fight bosses”).
  • Understand why it’s fun
    • Not just “it feels good,” but what underlying motivation/structure makes players keep playing.
  • It’s replayable
    • Even short prototypes should support repeated sessions where you naturally want to try again and generate new ideas.
  • It provides closure
    • Either it convinces you to continue, or it clearly shows why you shouldn’t—so you stop daydreaming and move on without regret.

Strategies for low-effort marketing validation (short-form)

  • Record quick gameplay clips (≈10–15 seconds) once you have something playable.
  • Share on short-form platforms (examples mentioned):
    • Discord / Twitter
    • YouTube Shorts / TikTok
  • Keep it deliberately simple (e.g., phone recording, portrait mode, a quick caption like “I prototyped this”) to test organic reactions.
