Do you play with Occults?

To sum it up - if I don't have at least one occult sim in a play through, something is wrong... I loved mixing different occult states in 3 to create some kind of hybrid, and sometimes adding traits that clash to go with other occult sims in the household. Not an entirely bad way to spice up a boring 10-gen story, especially when baby sis finally grows into her fangs and suddenly comes home with an Alien to meet the family. :p
