Walking around this neighborhood in what is now 2015, you were 17, and was looking for something to jog your memory in the garage, as you decided to have a garage sale, when a glimmer of a cartridge caught your eye, you pull it out and you cant believe it, its the Sonic 1996 movie you thought you lost. So, just for the sake of good memories, you decide to keep it, and later in the night, boot it up, as a rush of nostalgia hits you at that start screen, however it feels like... this also could might include you.... you dont know why you are thinking that, but you feel giddy remembering how cool Sonic was to you as a kid, and that you may want to help him someday
