Overview

The core game loop is a fundamental concept in game development that defines the set of actions players will spend most of their time doing in a game. It's crucial for designers and programmers to identify and define the core game loop early in the development process as it helps to focus the team's efforts, prioritize features, and optimize gameplay. The video emphasizes the importance of a well-defined core game loop for the success of a game, as it ensures a clear understanding of the game's mechanics and player engagement.

What is a Core Game Loop?
- 🕹️
  The core game loop consists of the most frequent and repeated actions players take in a game.
- 🔁
  It represents the primary gameplay pattern that players will experience throughout the game.
