Game Design “Frameworks”
• Paradigms for organizing our understanding.
![Page 4: Is this thing on?. Mechanics, Dynamics, Aesthetics A Formal Approach to Game Design Marc “MAHK” LeBlanc April 2003](https://reader030.vdocuments.site/reader030/viewer/2022032523/56649d805503460f94a64174/html5/thumbnails/4.jpg)
Game Design “Frameworks”
• Paradigms for organizing our understanding.
• Example Frameworks:– The 400 Project– Design Patterns
![Page 5: Is this thing on?. Mechanics, Dynamics, Aesthetics A Formal Approach to Game Design Marc “MAHK” LeBlanc April 2003](https://reader030.vdocuments.site/reader030/viewer/2022032523/56649d805503460f94a64174/html5/thumbnails/5.jpg)
Game Design “Frameworks”
• Paradigms for organizing our understanding.
• Example Frameworks:– The 400 Project– Design Patterns
• Separate from the process.
![Page 6: Is this thing on?. Mechanics, Dynamics, Aesthetics A Formal Approach to Game Design Marc “MAHK” LeBlanc April 2003](https://reader030.vdocuments.site/reader030/viewer/2022032523/56649d805503460f94a64174/html5/thumbnails/6.jpg)
Our Framework
• Organized around the designer-player relationship.
• Grounded in a formal approach.

The difference is the way that games are consumed.
![Page 17: Is this thing on?. Mechanics, Dynamics, Aesthetics A Formal Approach to Game Design Marc “MAHK” LeBlanc April 2003](https://reader030.vdocuments.site/reader030/viewer/2022032523/56649d805503460f94a64174/html5/thumbnails/17.jpg)
An Extreme Opposite Example:A Theatrical Play
The “design team” knows:
• Script
• Lighting
• Acoustics
• Seating
• Intermissions
![Page 18: Is this thing on?. Mechanics, Dynamics, Aesthetics A Formal Approach to Game Design Marc “MAHK” LeBlanc April 2003](https://reader030.vdocuments.site/reader030/viewer/2022032523/56649d805503460f94a64174/html5/thumbnails/18.jpg)
Games, on the Contrary
The designer doesn’t know:
• When will the player play? How often? For how long?
• Where? With Whom?
And most importantly...
• What will happen during the game?
![Page 19: Is this thing on?. Mechanics, Dynamics, Aesthetics A Formal Approach to Game Design Marc “MAHK” LeBlanc April 2003](https://reader030.vdocuments.site/reader030/viewer/2022032523/56649d805503460f94a64174/html5/thumbnails/19.jpg)
Obligatory Editorial
This lack of predictability is the essence of play. It should be embraced, not eschewed.
![Page 20: Is this thing on?. Mechanics, Dynamics, Aesthetics A Formal Approach to Game Design Marc “MAHK” LeBlanc April 2003](https://reader030.vdocuments.site/reader030/viewer/2022032523/56649d805503460f94a64174/html5/thumbnails/20.jpg)

Definitions
• Mechanics: The rules and concepts that formally specify the game-as-system.
• Dynamics: The run-time behavior of the game-as-system.
• Aesthetics: The desirable emotional responses evoked by the game dynamics.
![Page 26: Is this thing on?. Mechanics, Dynamics, Aesthetics A Formal Approach to Game Design Marc “MAHK” LeBlanc April 2003](https://reader030.vdocuments.site/reader030/viewer/2022032523/56649d805503460f94a64174/html5/thumbnails/26.jpg)
The Building Blocks: Formal Models
• No Grand Unified Theory
• Instead, lots of little models
• Models can be formulas or abstractions.
• We can think of models as “lenses.”
• Discovering new models is an ongoing process.
![Page 27: Is this thing on?. Mechanics, Dynamics, Aesthetics A Formal Approach to Game Design Marc “MAHK” LeBlanc April 2003](https://reader030.vdocuments.site/reader030/viewer/2022032523/56649d805503460f94a64174/html5/thumbnails/27.jpg)
MDA is a “Taxonomy” for Models
• Knowledge of Aesthetics
• Knowledge of Dynamics
• Knowledge of Mechanics
• Knowledge of the interactions between them.
![Page 28: Is this thing on?. Mechanics, Dynamics, Aesthetics A Formal Approach to Game Design Marc “MAHK” LeBlanc April 2003](https://reader030.vdocuments.site/reader030/viewer/2022032523/56649d805503460f94a64174/html5/thumbnails/28.jpg)
Properties of Good Models
We want our models to be:
• Formal (i.e. well-defined).
• Abstract (i.e. widely applicable).
• Proven (i.e. known to work).
On any given game, we expect to use several different abstractions, not one big one.
![Page 29: Is this thing on?. Mechanics, Dynamics, Aesthetics A Formal Approach to Game Design Marc “MAHK” LeBlanc April 2003](https://reader030.vdocuments.site/reader030/viewer/2022032523/56649d805503460f94a64174/html5/thumbnails/29.jpg)
Part III: MDA in detail
In this part, we discuss Aesthetics, Dynamics and Mechanics in detail.

Understanding Aesthetics
We need to get past words like “fun” and “gameplay.”
• What kinds of “fun” are there?
• How will we know a particular kind of “fun” when we see it?
![Page 33: Is this thing on?. Mechanics, Dynamics, Aesthetics A Formal Approach to Game Design Marc “MAHK” LeBlanc April 2003](https://reader030.vdocuments.site/reader030/viewer/2022032523/56649d805503460f94a64174/html5/thumbnails/33.jpg)

Clarifying Our Aesthetics
• Charades is “fun.”
• Quake is “fun.”
• Final Fantasy is “fun.”
![Page 43: Is this thing on?. Mechanics, Dynamics, Aesthetics A Formal Approach to Game Design Marc “MAHK” LeBlanc April 2003](https://reader030.vdocuments.site/reader030/viewer/2022032523/56649d805503460f94a64174/html5/thumbnails/43.jpg)
Clarifying Our Aesthetics
• Charades: Fellowship, Expression, Challenge
• Quake: Challenge, Sensation, Competition, Fantasy
• Final Fantasy: Fantasy, Narrative, Expression, Discovery, Challenge, Masochism
• Each game pursues multiple aesthetics.
• Again, there is no Grand Unified Theory.
![Page 44: Is this thing on?. Mechanics, Dynamics, Aesthetics A Formal Approach to Game Design Marc “MAHK” LeBlanc April 2003](https://reader030.vdocuments.site/reader030/viewer/2022032523/56649d805503460f94a64174/html5/thumbnails/44.jpg)
Clarifying Our Goals
• As designers, we can choose certain aesthetics as goals for our game design.
• We need more than a one-word definition of our goals.
![Page 45: Is this thing on?. Mechanics, Dynamics, Aesthetics A Formal Approach to Game Design Marc “MAHK” LeBlanc April 2003](https://reader030.vdocuments.site/reader030/viewer/2022032523/56649d805503460f94a64174/html5/thumbnails/45.jpg)
What is an “Aesthetic Model?”
• A rigorous definition of an aesthetic goal.
• Serves as an “aesthetic compass.”
• States criteria for success as well as possible modes of failure.
Some examples…
![Page 46: Is this thing on?. Mechanics, Dynamics, Aesthetics A Formal Approach to Game Design Marc “MAHK” LeBlanc April 2003](https://reader030.vdocuments.site/reader030/viewer/2022032523/56649d805503460f94a64174/html5/thumbnails/46.jpg)
Goal: Competition
Model: A game is competitive if:• Players are adversaries.• Players have an ongoing emotional investment in
defeating each other.
Some Failure Modes:• A player feels that he can’t win.• A player can’t measure his progress.
![Page 47: Is this thing on?. Mechanics, Dynamics, Aesthetics A Formal Approach to Game Design Marc “MAHK” LeBlanc April 2003](https://reader030.vdocuments.site/reader030/viewer/2022032523/56649d805503460f94a64174/html5/thumbnails/47.jpg)
Goal: Realistic Flight Simulation
Possible Models: Our flight dynamics are realistic if:
• They match a mathematical formula, or,• They pass our “realism checklist,”
Failure Modes:
• Counter-intuitive system behavior.
![Page 48: Is this thing on?. Mechanics, Dynamics, Aesthetics A Formal Approach to Game Design Marc “MAHK” LeBlanc April 2003](https://reader030.vdocuments.site/reader030/viewer/2022032523/56649d805503460f94a64174/html5/thumbnails/48.jpg)
Goal: Drama
Model: A game is dramatic if:• Its central conflict creates dramatic tension.• The dramatic tension builds towards a climax.

Goal: Drama
Failure Modes:• No dramatic tension.• Tension does not increase towards a climax.

![Page 50: Is this thing on?. Mechanics, Dynamics, Aesthetics A Formal Approach to Game Design Marc “MAHK” LeBlanc April 2003](https://reader030.vdocuments.site/reader030/viewer/2022032523/56649d805503460f94a64174/html5/thumbnails/50.jpg)
Understanding Dynamics
• How can we predict and explain the behavior of the game-as-system?
![Page 51: Is this thing on?. Mechanics, Dynamics, Aesthetics A Formal Approach to Game Design Marc “MAHK” LeBlanc April 2003](https://reader030.vdocuments.site/reader030/viewer/2022032523/56649d805503460f94a64174/html5/thumbnails/51.jpg)

Models of Game Dynamics
• Again, no Grand Unified Theory
• Instead, a collection of many Dynamic Models.
• Dynamics models are analytical in nature.
Some examples…
![Page 53: Is this thing on?. Mechanics, Dynamics, Aesthetics A Formal Approach to Game Design Marc “MAHK” LeBlanc April 2003](https://reader030.vdocuments.site/reader030/viewer/2022032523/56649d805503460f94a64174/html5/thumbnails/53.jpg)

Example: Operant Conditioning
• The player is part of the system, too!
• Psychology gives us models to explain and predict the player’s behavior.

Where Models Come From
• Analysis of existing games.
• Other Fields: Math, Psychology, Engineering…
• Our own experience.
On to Mechanics...
![Page 57: Is this thing on?. Mechanics, Dynamics, Aesthetics A Formal Approach to Game Design Marc “MAHK” LeBlanc April 2003](https://reader030.vdocuments.site/reader030/viewer/2022032523/56649d805503460f94a64174/html5/thumbnails/57.jpg)
Understanding Mechanics
• There’s a vast library of common game mechanics.
![Page 58: Is this thing on?. Mechanics, Dynamics, Aesthetics A Formal Approach to Game Design Marc “MAHK” LeBlanc April 2003](https://reader030.vdocuments.site/reader030/viewer/2022032523/56649d805503460f94a64174/html5/thumbnails/58.jpg)
Examples
• Cards: Shuffling, Trick-Taking, Bidding

Mechanics vs. Dynamics
We need to acknowledge mechanics and dynamics as distinct concepts.
Dynamics emerge from Mechanics.
![Page 60: Is this thing on?. Mechanics, Dynamics, Aesthetics A Formal Approach to Game Design Marc “MAHK” LeBlanc April 2003](https://reader030.vdocuments.site/reader030/viewer/2022032523/56649d805503460f94a64174/html5/thumbnails/60.jpg)
Interaction Models
• How do specific dynamics emerge from specific mechanics?
• How do specific dynamics evoke specific aesthetics?
![Page 61: Is this thing on?. Mechanics, Dynamics, Aesthetics A Formal Approach to Game Design Marc “MAHK” LeBlanc April 2003](https://reader030.vdocuments.site/reader030/viewer/2022032523/56649d805503460f94a64174/html5/thumbnails/61.jpg)
Example: Time Pressure
• “Time pressure” is a dynamic.
• It can create dramatic tension.
• Various mechanics create time pressure: – Simple time limit– “Pace” monster– Depleting resource

Moving Forward…
Let’s hope the future brings us:
• A rich aesthetic vocabulary.
• A eclectic library of game mechanics.
• A catalog of formal models: Aesthetic, Dynamic, Interaction
In other words,
“Formal Abstract Design Tools.”

The Three Musketeers
...and the Dynamics of Drama
![Page 64: Is this thing on?. Mechanics, Dynamics, Aesthetics A Formal Approach to Game Design Marc “MAHK” LeBlanc April 2003](https://reader030.vdocuments.site/reader030/viewer/2022032523/56649d805503460f94a64174/html5/thumbnails/64.jpg)
Rules for Three Musketeers
• Players take turns moving one of their pieces. No diagonal moves.
• Musketeers move by capturing a nearby enemy.
• Cardinal’s men move to a nearby empty space.
• Cardinal wins if the Musketeers are in the same row or column.
• Musketeers win if they cannot move.

The Dramatic Arc Pervades Game Aesthetics
• Challenge: Obstacle/Triumph
• Discovery: Novelty/Mastery
• Submission: Toil/Reward
• Competition: Equality/Supremacy
![Page 78: Is this thing on?. Mechanics, Dynamics, Aesthetics A Formal Approach to Game Design Marc “MAHK” LeBlanc April 2003](https://reader030.vdocuments.site/reader030/viewer/2022032523/56649d805503460f94a64174/html5/thumbnails/78.jpg)
So Games are Stories, Right?
![Page 79: Is this thing on?. Mechanics, Dynamics, Aesthetics A Formal Approach to Game Design Marc “MAHK” LeBlanc April 2003](https://reader030.vdocuments.site/reader030/viewer/2022032523/56649d805503460f94a64174/html5/thumbnails/79.jpg)
So Games are Stories, Right?
• Rather, Play and Narrative intersect.
![Page 80: Is this thing on?. Mechanics, Dynamics, Aesthetics A Formal Approach to Game Design Marc “MAHK” LeBlanc April 2003](https://reader030.vdocuments.site/reader030/viewer/2022032523/56649d805503460f94a64174/html5/thumbnails/80.jpg)
So Games are Stories, Right?
• Rather, Play and Narrative intersect.
• The Dramatic Arc is the point of intersection.
![Page 81: Is this thing on?. Mechanics, Dynamics, Aesthetics A Formal Approach to Game Design Marc “MAHK” LeBlanc April 2003](https://reader030.vdocuments.site/reader030/viewer/2022032523/56649d805503460f94a64174/html5/thumbnails/81.jpg)
So Games are Stories, Right?
• Rather, Play and Narrative intersect.
• The Dramatic Arc is the point of intersection.
• Drama is more “primal” than narrative.
![Page 82: Is this thing on?. Mechanics, Dynamics, Aesthetics A Formal Approach to Game Design Marc “MAHK” LeBlanc April 2003](https://reader030.vdocuments.site/reader030/viewer/2022032523/56649d805503460f94a64174/html5/thumbnails/82.jpg)
So Games are Stories, Right?
• Rather, Play and Narrative intersect.
• The Dramatic Arc is the point of intersection.
• Drama is more “primal” than narrative.
• Games don’t tell stories, they are stories.

Drama in Detail
Drama Requires:
• Dramatic Tension
• Rising and Falling Action
![Page 84: Is this thing on?. Mechanics, Dynamics, Aesthetics A Formal Approach to Game Design Marc “MAHK” LeBlanc April 2003](https://reader030.vdocuments.site/reader030/viewer/2022032523/56649d805503460f94a64174/html5/thumbnails/84.jpg)
Drama in Detail
Drama Requires:
• Dramatic Tension– Uncertainty– Inevitability
• Rising and Falling Action
![Page 85: Is this thing on?. Mechanics, Dynamics, Aesthetics A Formal Approach to Game Design Marc “MAHK” LeBlanc April 2003](https://reader030.vdocuments.site/reader030/viewer/2022032523/56649d805503460f94a64174/html5/thumbnails/85.jpg)
Dramatic Tension
• Uncertainty: The outcome is ambiguous
• Inevitability: The outcome is imminent.
![Page 86: Is this thing on?. Mechanics, Dynamics, Aesthetics A Formal Approach to Game Design Marc “MAHK” LeBlanc April 2003](https://reader030.vdocuments.site/reader030/viewer/2022032523/56649d805503460f94a64174/html5/thumbnails/86.jpg)
Drama in Three Musketeers
• Uncertainty: Search tree complexity
• Inevitability: Depletion of the Cardinal’s men
(consider “pushing” variant)
![Page 87: Is this thing on?. Mechanics, Dynamics, Aesthetics A Formal Approach to Game Design Marc “MAHK” LeBlanc April 2003](https://reader030.vdocuments.site/reader030/viewer/2022032523/56649d805503460f94a64174/html5/thumbnails/87.jpg)
Other Sources of Uncertainty
• Negative Feedback (“Crash Team Racing”)
• Rising Stakes (“Jeopardy”)
• Limited Information (“Warcraft”)
![Page 88: Is this thing on?. Mechanics, Dynamics, Aesthetics A Formal Approach to Game Design Marc “MAHK” LeBlanc April 2003](https://reader030.vdocuments.site/reader030/viewer/2022032523/56649d805503460f94a64174/html5/thumbnails/88.jpg)
Other Sources of Inevitability
• Non-reversible processes.
• Non-renewable resources.
• Perception is important.
![Page 89: Is this thing on?. Mechanics, Dynamics, Aesthetics A Formal Approach to Game Design Marc “MAHK” LeBlanc April 2003](https://reader030.vdocuments.site/reader030/viewer/2022032523/56649d805503460f94a64174/html5/thumbnails/89.jpg)
Denouement in Games
• Games need to resolve their tension.
• Some resolution happens outside the game.
• Many digital games build in post-game resolution.
![Page 90: Is this thing on?. Mechanics, Dynamics, Aesthetics A Formal Approach to Game Design Marc “MAHK” LeBlanc April 2003](https://reader030.vdocuments.site/reader030/viewer/2022032523/56649d805503460f94a64174/html5/thumbnails/90.jpg)
That’s All!
• Drama is a central play aesthetic.
• Drama is structured tension.
• Several different dynamics evoke uncertainty and inevitability.
