Simple vs Detailed game design document (GDD)

I created a comparison between a simple Game Design Document (GDD) and a detailed GDD, using the concept of an endless run game as the context.

What differentiates a simple GDD from a detailed GDD ?

Simple GDD:

• A simple GDD serves as an initial concept or a high-level overview of the game.
• Its primary purpose is to present the core ideas, features, and gameplay mechanics in a concise manner in order to secure approval from stakeholders or decision-makers before the production phase begins.
• This version of the GDD typically focuses on essential elements, such as the game's overall vision, basic gameplay loop, and key features. Since it is designed to be a quick reference, it doesn’t require much time to develop, usually taking around 1 to 2 days to create.
• The simple GDD is mainly used to communicate the concept and direction of the game, and is not as detailed or refined as the subsequent iterations.
• It serves as a preliminary document to ensure that the game concept aligns with the expectations of the project team and management before moving forward.

Detailed GDD:

• On the other hand, a detailed GDD comes into play once the initial concept has been approved. After receiving the green light to proceed with production, the detailed GDD becomes the living document that guides the entire development process.
• Unlike the simple GDD, which is focused on the overarching ideas, the detailed GDD provides an in-depth breakdown of every aspect of the game, including game mechanics, levels, art style, character designs, sound, user interface, and much more.
• It also outlines the specific requirements for programming, production schedules, and resource allocation.
• This version of the GDD is constantly updated throughout the development cycle to reflect changes, iterations, and new ideas as they emerge. It becomes a vital tool for coordinating between different departments (e.g., design, art, and programming) and ensuring that all elements of the game are aligned with the original vision.
• The detailed GDD plays a crucial role in facilitating communication and ensuring that the project remains on track throughout the production phase.
