Sonic Advance 3

Sonic Advance 3 (ソニックアドバンス3 Sonikku Adobansu 3) is a platform video game developed by Dimps and Sonic Team for the Game Boy Advance in 2004. The game stars the characters Sonic, Tails, Amy, Knuckles, and Cream as they seek to keep Doctor Eggman and his robot assistant Gemerl from building empires on each of seven chunks Eggman has divided the Earth into.

It's the last 2D Sonic game to use the original, San-Diego-based voice cast.
