There are two editions of the game, and I believe this is a later reprint. The cover inserts seem to be identical, but the disc labels are slightly different. This edition has white text and Nintendo logo, and longer disc code. It came with a manual, but it seems it did not come with (as many) additional paper items as the original release. The Wii instructions sheet is yellow.
