I used mods to ban any nonresident, like that insufferable Nancy Landgraab and Eliza Pancakes, out of Glimmerbrook and Forgotten Hollow. Having that option in game would be nice. I would also love to be able to link worlds. For example, I’ve got Newcrest and Magnolia Promenade set up as “Mooncrest,” a culturally diverse city of supernatural beings, and HOB as the village that Glimmerbrook is an extension of. It would be great to designate that the sims can freely travel between these worlds, but other sims can’t. That’s a lot of control, though.
