Final answer:
The post-production phase in game design involves refining, finalizing, and testing the game after its primary development to ensure it meets quality standards before release.
Step-by-step explanation:
The purpose of the post-production phase in game design is to finalize the game by editing content, adding special effects, music, and computer-generated imagery (CGI), as well as testing and refining the game based on feedback. This phase comes after the principal development stages and is crucial for ensuring that the game meets the desired quality standards before its release to the players. The post-production phase is not about creating a storyboard or testing the game before it is created; rather, it's about refining and finalizing the game after it has been created. This involves a process of prototype testing, making changes, and enhancement to improve the overall gaming experience.
