Sonic 2 itself is a very decent game. However, adding  Knuckles just makes the game that much worse... I mean, its just too Fun!!X) anyone who had the curiosity I had on 3 characters knows that their I for a treat(especially since you can switch between them. Sonia's Original Speed and Inst-shield, Tail's Flying, and Knuckles' gliding and climbing techniuqes make the perfect 3 man team!!



The difficulty is surely depending on how sly you are with the 3 characters, so I cant neccecarily give it a Straight 1 or 10 for difficulty..



Graphics are good and I certainly cant complain. But then again, in my perspective, Sonic is know for good Graphics.



Sound, good, bucause their music was catchy.



I gave depth a 10 simply because This game is easy to play, but taking full advantage of the stages and mastering it would also be very intriguing as well.

Last, All I can say is that its a game that you would definitely try again and again if you like platform games.
