Do Wii games have different boxes in Japan and USA(or other countries)?
I saw Super Mario Galaxy unboxing(Japanese version) and I realized that it got a cardboard box like old console games and then I looked for the USA version and no box.
Do Wii games have different in "looks" basing on the country it was produced? And also Different art on the box/casing?
Yes, box art usually varies by region, like the U.S., Japan, or Europe.
