In reply to Diondre Hill.
Truthfully, that’s probably all done in an attempt to try and encourage better sales in Japan, so that Sonic would ultimately sell a bit better over there than it traditionally does. The fact it doesn’t seem to be helping would only give Sega encouragement to keep trying.
It might also be a regional thing–it’s cheaper to produce and distribute such a bundle in Sega’s native Japan than it is to have to ship it all across the pond into the states to distribute.
