Zombies in TS3 creeped me out. I called the "inflected" sims from Strangerville zombies, and those are all the zombies I need! Though mummies are zombies and they would be cool.
I'm not interested in better plant sims or aliens. I do wish we had other types of water based occults, like selkies!
For me, the fairy need is met with the little glowy things in Sylvan glade, the little glowy things in discover university, the little glowy things in Komorebi, the island spirits in island living, etc. All I really want is wings to cosplay with. That's it. Just some pixie stuff in CAS.
I would love for some elemental based occults stuff. I was hoping spellcasters would be more weather based or elemental based. They can freeze and set fire to things, and mermaid can change the weather. But I would love to be able to make benders, (water, fire, earth, water) like in Avatar.
