I want to suggest that The Sims 4 finally bring back hybrid life states/occults like we had in previous Sims games.
Right now, the game has more occult types than any other entry in the franchise — vampires, spellcasters, mermaids, aliens, werewolves, ghosts, PlantSims, servos, etc. — but it artificially blocks players from combining them.
In The Sims 3, hybrids were a core part of supernatural gameplay. You could have vampire‑witches, fairy‑werewolves, ghost‑mermaids, and all kinds of unique combinations. It added depth, creativity, storytelling options, and made occult households feel dynamic instead of restricted.
The Sims 4 already tracks occult powers, weaknesses, needs, and animations. The only thing stopping hybrids is a hard-coded limitation that forces one occult to overwrite another. Removing that limitation would immediately open up far more gameplay possibilities without breaking existing systems.
Please allow hybrid occults in The Sims 4. Let vampires be spellcasters. Let mermaids be aliens. Let werewolves be anything.
Occult players have been asking for this for years, and the game is more than capable of supporting it. Hybrids would make supernatural gameplay richer, more flexible, and more fun — just like it was in earlier Sims titles.
