Sonic Adventure is a lot of things. The best-selling Dreamcast game of all time. The console’s most popular launch title. Sonic’s best 3D outing? Okay, maybe not that last one. What do you think?

The Sonic Adventure 2 10th Anniversary Birthday Pack is a special collectible edition release of Sonic Adventure 2 which was sold only in Japan, and only on June 23rd and 24th in 2001 (the Blue Blur’s birthday).

Sega's party-game is fun with friends, not so much without. Either way, it’s not as good as Mario Party. But you can't play Mario Party on a Dreamcast!
