I was looking at the game called "Call of Duty Modern Warfare", on the mac app store, and it says that the game is for people age 12 and up, and it also says that it is only 7 GB of space required. But then I took a look at the actual disk on apple.com, and it says that it is for mature audiences only, and that it requires 9 GB of space on your hardrive. Does anyone know why the game is smaller on the mac app store, or if it is missing any levels from the full disk version? Also, do any of you guys know why the age would be different? Or is it just that 12 is when people are considered mature? Just a question. I think that some of the other games are like that also.
