Twenty years ago, on June 23, 1991, Sonic the Hedgehog 1 was released on the Genesis, and it marked the beginning of one of my favorite franchises as a kid (I still love Sonic to this day, by the way). Happy 20th Birthday, Sonic! Let's hope this year will be your best! What are you going to do for Sonic's birthday today? I know what I'm doing, I'm going to do some online races in Sonic & Sega All-Stars Racing, as well as replaying through levels in Sonic Colors, as I am trying to get a couple of S Ranks in the game myself.
