Now that I have these, I can confirm that the discs have different
contents. Even the menus are different. Let's go through the
differences, shall we?
Image1: Cover image for Peach version features a male character. This
makes sense since the Peach version is marketed "for girls."
Image2: In contrast, Sky version features a female character on the
cover.
Image3: Peach's tri-fold pack contains two postcards, a booklet, and
some band-aid. That's right! Band-aid! Notice how the female
character image is on the DVD silkscreen. Not seen in the image is a
makeup pen also included in the package.
Image4: Sky's quad-fold pack contains 10 picture cards, a booklet, and
an instruction for making your own character-cards from the picture
cards and the blank cards that are included. The booklet is identical
in both versions. Notice how the male character image is on the DVD
silkscreen. Basically, the cover image and the DVD silkscreen image
are reversed between the two versions.
Image5: Screenshot from the special video clip, only available in the
Peach version. That's the director and Miyamoto Shun'ichi (singer of
the opening theme). Apple sure is popular in Japan.
Image6: Recording of the opening theme.
So, there we have it. To put it bluntly, Peach version is cheaper, has more video content, and has more useful items. You never know when a band-aid might come in handy. Seriously, those picture cards in Sky version are useless because most people wouldn't dare cut up the cards to make character-cards. I will be following their video contents carefully and choose based on that. After all, video content is the most important part of these DVDs.
