Yeah I remember asking Namco support about that and they said the same thing but at first they didnt know anything about it. They had to look into it to find out it was a second printing. I wasnt sure if they were just saying that to satisfy me and stop bugging them or not.
It just seems weird to make completely different disc art. I dont know any games that do that especially not a Tales game where it might not sell as well as they expect.
