Have pretty much played lived in all the worlds except for Mt. Komorebi which I use as a vacation world and only touched a little bit of the newer worlds San Sequoia and Tomarang as right now no one is moving out where they are. When have someone ready to will place on half the lots community and neighbours and my sims will live on the other lots
Occults pretty much stay in their own worlds, Aliens in Strangerville, weres in Moonwood Mill, Mermaids in Sulani, Spellcasters in Glimmerbrook and vampires in Forgotten Hollow if they marry another occult or husim then will decide stay in their current location, marry into their spouses or move elsewhere if they have roommates or family that lives with them. Pretty much decide with a wheel or dnd dice if they move or stay
