Sonic the Hedgehog 3 was released in early 1994, and in many ways is half finished. The other half of the game was released later in the year as Sonic and Knuckles. Sonic 3 can be locked onto Sonic and Knuckles to form the complete adventure. For this review, I'll be looking at Sonic 3 as a stand alone title. We'll look at Sonic and Knuckles in a future video.
