Buy Sonic and Knuckles, then you have Sonic the Hedghog 3 completed version!

Ok first before you play this game you have to have Sonic and Knuckles, just because it completes the game. In terms of difficulty *Carnival Night!*. I hated that level and trust me its relieving when you're in 3rd grade and you finally beat it (now sophmore in highschool). After that its easy. But wait you've got to get Sonic and Knuckles! Now your gaming experience in Sonic 3 is enhanced to its perfect form (because Sonic and Knuckles levels were supposed to be in Sonic 3, but the game wasn't complete by release date and Sega postponed it and released Sonic and Knuckles as its own game.) Now there that you have it you can play as Tails and the game is in its perfect form.
There you go great review but not much can be said. It was a great game and passed a lot of time for me and my brothers.
