Final answer:
Game discs are placed into their cases by automated machines during the manufacturing process, not manually by people. This allows for efficient and accurate mass production of video games.
Step-by-step explanation:
During the manufacturing of video games, people do not manually insert game discs into their cases. Instead, this task is accomplished by automated machines. The process includes printing the discs with the game data, checking them for quality assurance, and then using robotic systems to place the discs into their corresponding boxes along with any additional materials such as instruction booklets. This automation allows for the mass production of video games to meet high consumer demand, ensuring that each copy is packaged correctly and efficiently.
