Well, you\'re lucky. Many scracthed disks may seem to play fine, but then comes a cutscene.. it freezes. You load the game, try the cutscene again... freezes.
It\'s very annoying as in many games you can\'t skip the cut-scene or avoid it. So you\'ll just have to sell the game or copy a save-game past that cutscene from your friend.
This has happened to me.
