I recently got this game and heard it has a great value, does anyone know exactly "how" rare the game is, like the street value for it?

There was a limited edition?

Yes there was, but it is the hardest to find of all Sonic games, so many have not had luck on ebay(I got mine on ebay, I just got it with a lot of games and they did not say that it was a lim. ed., super lucky!) I have heard the main reason is because the original did not have the feature"Super Sonic" and lim. ed. does.
