Third GBA installment in SEGA's speedy platformer series. The game features five playable characters, and their vastly different abilities significantly change up the way each level is played. Sonic is balanced as a fast and furious runner, which makes him prime to beat the game quickly with the minimum requirements. But since this design puts a lot more focus on exploration and discovery by hiding little "chao" creatures in strategic locations all over the map, it's impossible to see everything without playing through each level multiple times. Players can use Sonic and Tails to beat the entire game at 100% and finish all seven worlds, but the fun is to open up the game with the three "hidden" characters Knuckles, Amy, and Cream. Other features include four-player link play and a cartridge save slot.
