My list is:
1. Faeries
2. Robots
3. Genie
4. PlantSims (something else)
5. Mermaids
6. Werewolves (basically tied with mermaids)
7. Imaginary Friends
I dislike zombies.
Also I don’t want witches or superheroes to be their own lifestates:
Witches because they look just like regular sim, and are basically exactly like them but with magic, and also you can’t change occult type in CAS.
And why shouldn’t an alien be allowed to be a superhero? Or a regular sim? Most superheroes are normal people who had something big happen to them (this also applies to super villains.) The Sims shouldn’t have to be Sky High or The Incredibles.
