Disney magic expansion

They'd need to get permission from Disney for that which would be a really long process. Also, I don't know if The Sims is a series they'd be willing to collab with. Not that The Sims is negative or anything, but Disney is mainly for young kids and The Sims seems a bit too mature for them.

If anything, they could just make their own fictional Disney-esque themed pack like they did with the Voidcritters. I'd personally love some princess dresses for girls in the game.
