It was obvious to everyone that it was only half a game given that you have this third character you see throughout the game that you can't play as (except in Competition Mode), and there only being 6 Zones to Sonic 2's 11. Because Capcom was pumping out one SFII revision after the next, people thought that SEGA was going to follow suit with either a Sonic 3 Special Edition or Sonic 4 to complete the other half of the story.
The OST was very well received, albeit the miniboss music feeling out of place.
