My favourite is Sonic The Hedgehog 3 and Knuckles.
Sonic and Knuckles is great but it is better with the Sonic 3 lock on.
I like this sonic game more than the other originals because the two of them to make a nice interesting pair. I like tails too but I had more fun playing the much stronger guys like sonic and knuckles.
Now that I think about it S&K is kinda like UMvC3...
Really? How so
Oh! I just looked up the history of the game. I didn't know it actually took place after Sonic 3. I always assumed that it was just an expansion with knuckles in it because there was never a Sonic 4 until now.
