Well can you tell me why so many PS3's have broken and the game people always played most was COD4?
It cannot simply be a coincidence. Not only that, its ALWAYS the same problem. Its always a disc reading error, and the last game the person plays is ALWAYS COD4.
Just go take a search on google and you will see what I mean, countless number of topics to do with COD4, broken PS3's and in particular, disc reading errors.
COD4 screws your disc drive/blue ray lens up and that is my final verdict, I am never going to play it.
