Game Design Fundamentals
The Core Loop
Every game has a core loop—the fundamental cycle players repeat:
ACTION → FEEDBACK → REWARD → MOTIVATION → ACTION
Example (Shooter):
Aim → Shoot → Hit/Miss feedback → Points/Progress → Aim again
Example (RPG):
Explore → Encounter → Combat → Loot/XP → Level up → Explore more
The MDA Framework
MECHANICS → DYNAMICS → AESTHETICS
(Rules) (Behavior) (Emotion)
What you build → How it plays → What players feel
Design forward: Mechanics → Dynamics → Aesthetics
Design backward: What feeling? → What behavior? → What rules?
Player Motivation (Bartle Types)
ACHIEVERS - Want to accomplish goals, collect, complete
EXPLORERS - Want to discover, understand, map
SOCIALIZERS - Want to interact, cooperate, compete with others
KILLERS - Want to dominate, defeat, impose will
Mechanics Design
Types of Mechanics
CORE MECHANICS:
What you do most often (shooting, jumping, building)
SECONDARY MECHANICS:
Support the core (inventory, upgrades, crafting)
PROGRESSION MECHANICS:
Drive forward motion (XP, unlocks, story beats)
SOCIAL MECHANICS:
Enable player interaction (trading, guilds, PvP)
Balancing
THE BALANCE TRIANGLE:
POWER
/\
/ \
/ \
COST ── UTILITY
Everything powerful should cost something.
Everything costly should provide utility.
Utility should feel worth the power/cost.
Risk/Reward
LOW RISK + LOW REWARD = Boring
LOW RISK + HIGH REWARD = Broken
HIGH RISK + LOW REWARD = Frustrating
HIGH RISK + HIGH REWARD = Thrilling
Find the sweet spot for your game.
Narrative Design
Interactive Storytelling
LINEAR:
Player experiences fixed story
(The Last of Us)
BRANCHING:
Player choices affect story
(Detroit: Become Human)
EMERGENT:
Story arises from systems
(Dwarf Fortress, RimWorld)
ENVIRONMENTAL:
Story told through world
(Dark Souls, Hollow Knight)
The Narrative Hook
MYSTERY - What is happening?
THREAT - What will happen?
DESIRE - What could I get?
BELONGING - Who are these people?
POWER - What can I become?
Ludonarrative Harmony
When mechanics and narrative align:
"I feel like a hero" + "My actions are heroic" = Harmony
When they conflict:
"I'm saving the world" + "I'm looting corpses" = Dissonance
Design mechanics that reinforce narrative.
Design narrative that justifies mechanics.
Systems Programming
Game Architecture Patterns
ENTITY-COMPONENT-SYSTEM (ECS):
Entities have components, systems process components
Best for: Data-oriented design, large worlds
OBJECT-ORIENTED:
Classes inherit behavior
Best for: Small to medium games, prototypes
STATE MACHINE:
States with transitions
Best for: AI, animation, game states
Performance Considerations
UPDATE LOOP:
Fixed timestep for physics
Variable timestep for rendering
Interpolation for smoothness
MEMORY:
Object pooling for frequent spawns
Spatial partitioning for queries
Level of detail for distant objects
CPU:
Batch similar operations
Avoid per-frame allocations
Profile before optimizing
Level Design
The Level Design Pillars
NAVIGATION - Can players find their way?
PACING - Does difficulty/intensity vary?
AESTHETICS - Does it look/feel right?
PURPOSE - Does it serve the game's goals?
Guiding Players
LANDMARKS - Distinctive visual features
LIGHTING - Bright = goal, dark = danger
ARCHITECTURE - Paths, walls, open spaces
COLOR - Warm = safe, cool = threat
SOUND - Music, ambient, directional cues

Quick Reference
Design Checklist
□ Core loop is clear and satisfying
□ Player motivations addressed
□ Mechanics reinforce fantasy
□ Narrative and mechanics align
□ Difficulty curve considered
□ Onboarding planned
□ End game considered
Common Pitfalls
□ Scope creep - Start small, expand later
□ Feature bloat - Every feature should serve core loop
□ Poor feedback - Player needs to know what happened
□ Unclear goals - Player needs to know what to do
□ Punishment without learning - Failure should teach
"A great game is not a collection of features. It's a carefully crafted experience where every element serves the player's journey."
