Core Mechanics Categories

Movement

Player locomotion through the game world.

Consider:

• Ground movement (walk, run, crouch, crawl)
• Aerial movement (jump, double jump, glide, fly)
• Swimming/water movement
• Climbing/vaulting
• Teleportation
• Speed curves and acceleration

Combat

Player vs player or player vs environment conflict.

Consider:

• Attack types (melee, ranged, magic)
• Damage calculation
• Hit detection
• Defense/blocking
• Hit points and damage
• Death/respawn

Interaction

How players manipulate objects and the world.

Consider:

• Pick up/drop items
• Use consumables
• Open doors/containers
• Activate switches/levers
• Talk to NPCs
• Craft items

Progression

How players advance and grow.

Consider:

• Experience points
• Leveling up
• Skill unlocks
• Stat increases
• Equipment acquisition
• Currency earning

Economy

How resources flow through the game.

Consider:

• Currency types
• Earning methods (faucets)
• Spending methods (sinks)
• Trading between players
• Vendor transactions

Mechanics Design Principles

Clarity

Mechanics should be:

• Discoverable - Players can learn through play
• Consistent - Same inputs produce same outputs
• Predictable - Experienced players can plan ahead

Depth

Mechanics should have:

• Skill ceiling - Room for mastery
• Counterplay - No unbeatable strategies
• Variety - Multiple valid approaches

Fairness

Mechanics should be:

• Balanced - No overpowered options
• Transparent - Rules are visible
• Forgiving - Mistakes aren't catastrophic

Common Mechanics Patterns

Rock-Paper-Scissors

Each option has a counter:

A beats B
B beats C
C beats A

Risk/Reward

Higher risk = higher potential reward:

Safe action → Low reward
Risky action → High reward

Resource Management

Limited resources force choices:

Resource pool → Action → Depletion
Regeneration method → Renewal

Progression Gates

Content unlocks over time:

Requirement → Unlock → New content

Balance Documentation

For each mechanic, document balance considerations:

Tuning Levers

Variables that can be adjusted:

| Lever | Current | Range | Effect | |-------|---------|-------|--------| | [Name] | [Value] | [Min-Max] | [Impact] |

Counterplay

What beats this mechanic:

| Situation | Counter | Why It Works | |-----------|---------|--------------| | [Scenario] | [Counter-strategy] | [Reasoning] |

Mechanics Review Checklist
