* Larger game files: The GOTY edition includes all the DLC released for Arkham City. This DLC content, including story missions, challenge maps, characters, and skins, significantly increases the game's file size. Two discs allow for a better distribution of the data.
* Improved loading times: Using two discs can help reduce loading times by allowing the game to access data from both discs simultaneously, improving performance.
* Physical media limitations: The standard DVD format has a maximum capacity of 4.7 GB, and Blu-ray discs have a capacity of 50 GB. Even with Blu-ray, the game and all the DLC content might exceed the storage limit, making two discs necessary.
Essentially, it's a practical approach to ensure all the content fits on the physical media and to provide a better gaming experience with quicker loading times.
