The MDA Framework

├─────────────────────────────────────────────────────────────┤
│  MECHANICS (Rules):                                          │
│  → Player actions, constraints, state changes               │
│  → Example: Jump has height limit, costs stamina            │

│  DYNAMICS (Behavior):                                        │
│  → Emergent gameplay from mechanic interactions             │
│  → Example: Wall-jump combos, speedrun routes               │
│                              ↓                               │
│  AESTHETICS (Experience):                                    │
│  → Emotional responses: Fun, tension, achievement           │
│  → Example: Flow state, satisfaction, immersion             │

Player Psychology

Bartle's Player Types

Type	Motivation	Design For
Achiever	Goals, progression	Achievements, levels
Explorer	Discovery, secrets	Hidden content, lore
Socializer	Community	Chat, guilds, co-op
Killer	Competition	PvP, leaderboards

Motivation Drivers

SELF-DETERMINATION THEORY:
┌─────────────────────────────────────────────────────────────┐
│  AUTONOMY:   Choice and control over actions               │
│  COMPETENCE: Mastery and skill demonstration               │
│  RELATEDNESS: Connection to characters/community           │
└─────────────────────────────────────────────────────────────┘

Reward Systems

REWARD TYPES:
┌─────────────────────────────────────────────────────────────┐
│  INTRINSIC (Internal):                                       │
│  • Achievement satisfaction                                 │
│  • Creative expression                                      │
│  • Curiosity fulfillment                                    │
│  • Skill mastery                                            │
├─────────────────────────────────────────────────────────────┤
│  EXTRINSIC (External):                                       │
│  • Points, scores                                           │
│  • Unlocks, cosmetics                                       │
│  • Leaderboard position                                     │
│  • Currency rewards                                         │
└─────────────────────────────────────────────────────────────┘

REWARD SCHEDULING:
• Fixed Ratio: Every N actions (predictable)
• Variable Ratio: Random timing (engaging but ethical concerns)
• Fixed Interval: Every N seconds
• Milestone: At progression checkpoints

Balance Principles

Aspect	Goal	Technique
Mechanical	All options viable	Counter-play, trade-offs
Economic	Meaningful scarcity	Sinks and faucets
Difficulty	Appropriate challenge	Dynamic scaling
Competitive	Fair play	Mirror balance, no dominance
