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:

code

A beats B
B beats C
C beats A

Risk/Reward

Higher risk = higher potential reward:

code

Safe action → Low reward
Risky action → High reward

Resource Management

Limited resources force choices:

code

Resource pool → Action → Depletion
Regeneration method → Renewal

Progression Gates

Content unlocks over time:

code

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]
