Aliens, Ghosts, Neither or Both?

I think I have 1 or 2 played aliens, no ghosts. None of my played sims have died yet. Most of my sims are vampires, though (also have a couple of kids/teens who are vamp/alien).

Would love to see fairies return, didn't care much for werewolves, mermaids or witches. But of course, if they are done right...
