Game Mechanics

What is a Game Mechanic?

Game mechanics are the rules and systems that define how players interact with a game.
They form the foundation of gameplay, influencing the player’s experience.

Game mechanics are defined as any action performed by a player that modifies the game state, that is, the position and specific characteristics

of all objects and environments present in the game at a precise moment in time. The game state, or state of the video game,

is modified due to one of the defining characteristics of games: interactivity.

Examples:

Jumping in platformers (e.g., Super Mario Bros.).
- Shooting and cover systems in FPS games (e.g., Call of Duty).
- Resource management in strategy games (e.g., Civilization).

Game mechanics tend to be simple: when you win a battle, you get a prize and get a certain position in a leaderboard where your rivals also are.

Some games may have the same mechanic but with different consequence. For example a crouch mechanic in a game like Assassins creed will work as part of a sneak mechanic, making the player more difficult to see to the enemy. However crouch in a first person shooter will give the player a smaller hit box. Making it harder to other players to shoot them.

Game Mechanic Types

Core Mechanics: The primary actions players take, such as moving, jumping, or shooting.
Progression Mechanics: Systems that track and reward progress, like leveling up or unlocking skills.
Resource Management Mechanics: Managing resources like health, ammo, or currency.
Social Mechanics: Multiplayer interactions like teaming up, trading, or PvP.
Challenge Mechanics: Obstacles or puzzles that test the player’s skills or thinking.

How to design mechanics

Concept Development:

Understanding the target audience and game goals.
Brainstorming mechanics that align with the game’s theme.

Prototyping:

Building small, testable versions of mechanics.
Iterating based on feedback.

Balancing:

Ensuring fairness and challenge.
Adjusting difficulty levels, rewards, and penalties.

Integration:

Combining mechanics to create cohesive gameplay.
Testing interactions between mechanics.
