Sonic the Hedgehog 3 1994

Is it still worth playing?

Sega Technical Institute's 1994 side scrolling platformer for the Genesis, in which Sonic and Tails try to collect the Chaos Emeralds to stop Doctor Robotnik from relaunching his crashed Death Egg. There are six zones, each with two acts that end in a miniboss and then a boss fight. You control Sonic while Tails follows, and a second player can control Tails, who can fly briefly and swim underwater, which Sonic cannot. Rings serve as health, and monitors grant power ups such as shields and extra lives. There are two kinds of bonus stage, a gumball machine style stage for power ups and 3D blue sphere stages for earning Chaos Emeralds, and collecting all seven lets Sonic transform into Super Sonic. It was the first appearance of Knuckles the Echidna. A second player who flies and swims as Tails shares the same stages, so it is still a game for two.
