User blog:Pacmansonic138/Sonic & SEGA All-Stars Racing, RE-RATED?

As Sonic fans we all know about the game Sonic & SEGA All-Stars Racing, but on the back of the Sonic Generations instruction manual, it shows a different ESRB rating. Isn't this weird, this is the only Sonic-related game so far that has been re-rated, but this could be a mistake.
