Sony Online Entertainment and the Free Realms teams have announced that the game has scored over twenty million registrations since launch in 2009.
To celebrate the momentous occasion, every character on a player's account will receive a special letterman's jacket provided they log into Free Realms between October 21-31.
While there, players can also take advantage of the holiday happenings. There is a Vampire vs Wolf Dance Off and a new werewolf mount for traveling in style.
