The Sims 3 is not exactly a stranger terrible things - we first saw the vampires in Late Night expansion, for example, and the ghosts have been around since the beginning - but Supernatural allows for greater freedom of the concepts by the removal of the many requirements that are used to with them. Instead of waiting for the sim to die in order to make a ghost or get chewed to produce a vampire, you can fill your family with vampires and ghosts directly from Create-A-Sim screen, along with other options, such as fairies, werewolves, witches and zombies.
