Do you play with Occults?

In a game where all sims' behaviour is pretty much the same regardless of their traits, and pets were quite the disappointment (to me, anyway), occults add some much needed variation to normal gameplay.

Back in TS2, the only occults I liked were witches, because most of the others were basically just normal sims with skin conditions, and ghosts weren't even playable. TS4 has fleshed out aliens and vampires, ghosts are finally playable (although they might already have been in TS3, I don't know), and I'm positive that any future occult life states will get a similar treatment. Plant sims are lame this time around, and I think ghosts could have had more unique options, but still.
