I certainly do see your point, but what I also have in mind are the complications that could occur, which would break the standard formating.
A title like Goofy's example is perfectly fine and would work, if it weren't for games like i.e. Disney's Hercules Action Game. "Action Game" is not written on the cover as a part of the main title and are therefore to be taken as a subtitle - making the title (following Goofy's example) to be like "Disney's: Hercules: Action Game".. and that looks way wrong in my eyes
EDIT: The game as reference
