This limited edition birthday item is a special package sold by Sega
in 2001 to mark the tenth anniversary of Sonic the Hedgehog
's adventures. The package was only available to those who preordered Sonic Adventure 2
for the Sega Dreamcast
and included the Sonic Adventure 2
game, a special golden CD
from the Sonic the Hedgehog
series, a commemorative Sonic
coin, and a booklet detailing the history of Sonic the Hedgehog
. It was all packaged in a special blue box.
The gold CD contains game music from Sonic the Hedgehog, Sonic the Hedgehog 2, Sonic the Hedgehog 3, Sonic and Knuckles, Sonic CD, Sonic R, Sonic Adventure, and the final track is a medley of vocal songs from Sonic Adventure 2.
The package is long out of distribution and anyone hoping to find one should check out online auctions. The game itself, of course, is more commonly available.
