PS2: Ys -The Ark of Napishtim versions?

[HHarm]

Any idea what the difference is between:


Ys -The Ark of Napishtim- (Limited Edition) (Japan Version)

and

Ys -The Ark of Napishtim- (First Press Limited Edition) (Japan Version)


There is a price difference. Both seem to be according to the shipping weight big box versions. Any idea?
