I had already shown this around some Sonic scenes prior, and there's some degree of familiarity with it, but regardless... :P

A preview of "Sonic the Hedgehog" for MegaDrive. If you watch closely, you can see some minor discrepancies from what the final version is like.

I heard the similar "Sonic 3" preview is upped already...
