Hey, Retro. :D I saw this on Ebay recently, and I was wondering if there were any distinct differences between this version, and the more 'mainstream,' one. <a href="http://cgi.ebay.com/Sega-Genesis-Sonic-Hedgehog-Complete-/350443256850?pt=Video_Games_Games&hash=item51980bbc12" target="_blank">http://cgi.ebay.com/Sega-Genesis-Sonic-Hed...=item51980bbc12</a> I have the 'not for resale,' version, but am thinking heavily of getting this one. I know there are many revisions of Sonic the Hedgehog, but is this one that's a different revision? Thanks for your time, Retro. Discuss different revisions of Sonic the Hedgehog, or any other Sonic game(s) for that matter.
