Why is modularity important in game development?

Modularity is crucial in game development because it promotes code reuse and simplifies maintenance. When a game is designed with modular components, each part of the game can be developed, tested, and updated independently. This separation allows developers to identify and fix issues within specific modules without affecting the entire codebase.

For example, if a developer wants to enhance a character's movement system, they can do so by modifying only the relevant module, leaving other parts of the game untouched. This approach not only makes it easier to manage the code but also supports collaborative work within a team, as different members can work on different modules simultaneously without conflicts.

Additionally, if a module needs to be used in another project, modular design allows for easy integration, saving time and resources that would otherwise be spent on rewriting code. Thus, the benefits of modularity align closely with enhancing productivity and maintaining a high-quality codebase throughout the game's development lifecycle.
