Picture this: There's a genie lamp you can find/purchase with points/be given. Rubbing it will release the genie inside, who will grant you three wishes. Those wishes can either be granted as the sim wants, or fail and mess them up. Releasing the genie adds them to your household. Nothing new so far.
But when they're played, they can grant wishes. They can choose if they want to grant a wish properly, or if they make a wish with a dark twist. Either way every wish they grant successfully will give them experience. They have a perk tree that will increase the amount of wishes they can grant, influence their wishing success rate, and maybe some other perks like turning the lower half of their body into smoke, teleportation, the ability to turn others into genies, etc. This is balanced by having an magic meter, so you can't just make a bunch of genies and spam wishes until you're a billionaire. More experienced genies can get perks that allow them to grant more wishes. Further, they can only grant one sim a single wish a day.
So now you can play as a genie, granting wishes or sewing chaos all across the sim world.
