## TL;DR

Core mechanics connect player inputs, game-state updates, feedback, and higher-level dynamics into a playable system.

## Core Explanation

Mechanics define the player-facing rules, while loops and state patterns provide implementation structures for progressing and organizing those rules during play.

## Source-Mapped Facts

- The MDA framework analyzes games through mechanics, dynamics, and aesthetics as linked layers of game design. ([source](https://users.cs.northwestern.edu/~hunicke/MDA.pdf))
- Game Programming Patterns describes a game loop as repeatedly processing input, updating game state, rendering, and tracking time during gameplay. ([source](https://gameprogrammingpatterns.com/game-loop.html))
- Game Programming Patterns presents the State pattern as a way for an object to alter behavior when its internal state changes. ([source](https://gameprogrammingpatterns.com/state.html))
