Idea: Superhero/Villain and Royalty Expansion Packs with Save Toggles

I think a simple World Toggle System would let players enjoy Royalty or Superhero gameplay without changing every save. When you start a brand-new save, you’d pick one of four world types:

Regular (Classic Sims): Everything works as it does now.

Royalty Save: Unlocks a castle-themed world and assigns titles (king, queen, emperor, empress, duke, duchess, etc.) to some NPCs. Everyone else is a commoner.

Superhero/Villain Save: Unlocks a comic-style city where a few NPCs gain superhero or villain roles along with superpowers. The rest are ordinary citizens, because not everyone in a Marvel or DC universe is flying around in a cape.

Both Royalty + Superhero: If you own both packs, you can enable both systems in the same save, giving you access to both themed worlds and role types.

Your choice affects only that save file and existing worlds like Sulani, Willow Creek, etc. stay exactly the same. Sulani won’t suddenly sprout castles, and Oasis Springs won’t be crawling with masked vigilantes. If you choose Royalty or Superhero mode, an extra themed world appears just for that save. If you pick a Regular save, those themed worlds could still be available, but they’d behave like standard worlds (no titles or superpowers).

CAS integration:

In a Royalty save, CAS would show a dropdown (next to relationships and pronouns) where you can assign a title to your Sim or leave them as a commoner.

In a Superhero save, that same slot lets you mark a Sim as a hero or villain, or leave them an ordinary citizen. If you choose hero or villain, a new panel (like the aspiration or trait section) appears to let you select their superpowers.

When you hit Play, the game automatically assigns a few NPCs appropriate titles or hero/villain roles so you don’t have to.

All clothing, furniture, and Build/Buy items from these packs would remain available in every save, no matter what world type you choose.

This idea would also make Royalty and Superheroes work more like gameplay roles rather than occults, so you could still have the option to make a mermaid queen or an alien superhero. If they were occults instead, you’d be stuck choosing one or the other, making it feel limited as to what you can actually do and create.

I’m not a modder or a dev—just someone sharing an idea in case it sparks discussion or inspires someone who can make it happen. If anything ever comes of it, I’d appreciate credit for the concept.

I also posted this on Reddit to see what people there think too. It’s probably a long shot that EA or anyone else notices, but it can’t hurt to get the conversation going.
