My favourite life state would be witches - I swear it has nothing to do with my username I like how they don't look any different from regular sims but have so many abilities. In the Sims 2 I remember how every time a witch/warlock cast a spell they would change into a ridiculous outfit.
Totally agree! i hate the skin tones from the Genie, etc. I don't want wings hanging of my sim's back. The werewolves et like pigs and have horrible faces when they turn (plus when they get wet, everyone gets a negtive "wet dog" moodlet. Vampires are restricted to being out only at night. IF's are useless, and often times have rotten traits. Simbots, eat up your quota for sims in the household, and since they have feelings can get angry, etc.
Now, if I can have a hybrid, I'd want it to have witch and alien abilities (without the alien skin and eyes)! Watch out humans!
