The MDA Framework

Mr. John Jennings

Introduction

The MDA Framework provides a vocabulary for discussing play and addresses the gap between ideas and game mechanics. This formal approach, developed by LeBlanc et al. since 2001, gives game designers a systematic way to understand how games create meaningful experiences for players.

Note

MDA stands for Mechanics, Dynamics, and Aesthetics - three interconnected layers that explain how games function and create emotional responses.

Understanding the Gap: From Cards to Drama

Consider this fundamental question in game design: How do we get from simple components like cards and rules to complex experiences involving intrigue, challenge, and drama?

The answer lies in understanding the causal link that sets games apart from other forms of media. Games are unique because they create emergent experiences through the interaction of systems and players.

The MDA Framework Defined

Mechanics

The rules and concepts that formally specify the game-as-system. These are the foundational elements that define what players can and cannot do within the game world.

Dynamics

The run-time behaviour of the game-as-system + players. This is what actually happens when the mechanics interact with player decisions and actions during gameplay.

Aesthetics

The emotional responses evoked by the game dynamics. These are the feelings and experiences that emerge from the interaction between the game system and the players.

Tip

Think of MDA as a taxonomy of design knowledge that helps us understand not just the individual components, but the crucial interactions between them.

The Designer/Player Relationship

The MDA framework reveals an important asymmetry in how designers and players experience games:

The Player’s Perspective

Players experience games from Aesthetics → Dynamics → Mechanics. They first feel the emotional impact, then understand the gameplay patterns, and finally (if at all) comprehend the underlying rule systems.

The Designer’s Perspective

Designers work from Mechanics → Dynamics → Aesthetics. They create rules, anticipate how those rules will play out in practice, and hope to achieve specific emotional responses.

Warning

This asymmetry is why playtesting is crucial - designers must verify that their mechanical choices actually produce the intended aesthetic experiences.

Practical Application: The Bartok Experiment

Let’s examine how MDA works in practice through the card game Bartok:

Basic Bartok Rules

  • Deal 5 cards to each player
  • Turn over the top card of the deck
  • First person clockwise from the dealer goes
  • Play a card of the same suit or number, or draw a card
  • Jokers are wild
  • Play until someone has no more cards

Rule Modifications

Now consider these rule changes: 1. Cumulative Draw 2 cards: When a 2 is played, the next player must draw 2 cards or play another 2 2. See Last Card in Any Hand: Players can look at any opponent’s last remaining card 3. Out of Turn Play: Players can play out of turn if they have an exact match

Analyzing the Changes with MDA

Mechanics: The rule modifications are clear mechanical changes - new actions and conditions are added to the system.

Dynamics: These mechanical changes create new behavioral patterns: - Players become more strategic about when to play 2s - Information about opponents’ final cards changes decision-making - The turn order becomes more flexible and reactive

Aesthetics: The emotional experience shifts dramatically: - Increased tension when approaching the end of the game - More strategic depth and player agency - Greater social interaction and “gotcha” moments

Team Competition Variant

Consider how changing the win condition transforms the game entirely:

Modified Rules for Team Play

  • Every table plays Bartok with the enhanced rules
  • First table to finish wins (not individual players)
  • Cumulative Draw Two rule applies
  • Out of Turn Play allowed
  • Last Card Revealed to all players
  • No Table Talk permitted

MDA Analysis of Team Competition

This seemingly simple change to the win condition cascades through all three levels:

Mechanics: The victory condition shifts from individual to collective success.

Dynamics: Player behavior changes dramatically as cooperation becomes essential, yet communication is restricted.

Aesthetics: The emotional experience transforms from competitive individualism to collaborative tension under pressure.

Games as Software

The MDA framework helps us understand games as interactive systems, similar to software applications. Just as software has different layers of functionality, games have interconnected layers that work together to create the user experience.

Note

This systematic approach allows designers to “fail fast” - quickly identify when mechanical changes don’t produce the intended aesthetic outcomes and iterate accordingly.

Fiction and Aesthetics in Abstract Games

An interesting question emerges when analyzing abstract games like Bartok: Does Bartok even have a fiction? Could it?

While Bartok is mechanically abstract, it still generates aesthetic experiences through: - Social dynamics between players - Tension around hidden information - The satisfaction of strategic play - The excitement of close finishes

This demonstrates that aesthetics in games aren’t limited to narrative or thematic content - they can emerge from pure mechanical interaction.

Summary

The MDA Framework provides game designers with essential tools for understanding and creating meaningful play experiences:

  1. MDA creates a shared vocabulary for discussing how games work, bridging the gap between mechanical implementation and player experience.

  2. The framework reveals the asymmetry between designer and player perspectives, highlighting why playtesting and iteration are crucial to successful game design.

  3. Mechanical changes cascade through dynamics to aesthetics, meaning small rule modifications can dramatically alter the player experience.

  4. Even abstract games generate aesthetic experiences through the interaction of systems and social dynamics, not just through narrative content.

  5. Understanding these relationships enables rapid prototyping and iteration, allowing designers to fail fast and refine their designs more effectively.
