I tried 2 copies and could not get the game to play. With the first copy I was able to play the first few levels, then it froze up the PS3 at the beginning of the same level 10 times in a row. Gamefly quickly sent a replacement copy and the PS3 couldn't even load that one at all. I tried everything possible - removing or installing the update data, playing online or off, playing when the PS3 was hot or cold, etc. - and both discs were perfectly clean. Nothing is wrong with the PS3, I am not having trouble with freezing or glitching with any other games. The game is just broken.
