@Ziggyfin: Just trying to prevent people from being all "THEY ARE DIFFERENT GAMES AND YOU ARE STUPID. ALSO YOUR HAIRSTYLE MAKES YOU LOOK LIKE A GIRL."
@DSJ: No, Sonic CD is not on Mega Collection, nor is it on Mega Collection Plus. They only ways to play it short of emulating are the original Sega CD game, or as one of the three main games in Gems Collection.
Speaking of Gems Collection, we need a sequel to Sonic the Fighters. (Battle doesn't count, because it was bad.)
