Mine are roughly organized like in my build thread The World of Simmingal
(sort by oldest)
Occult worlds are close to all worlds magically
batuu and sixam can only be visited via rocket ship or magic being on different planets
otherwise its roughly like real map although america is very much juggled and everything is much closer together because all city worlds are just one san city
asian countries are close to each other by sea on separate islands but sulani and selvadorada are on one island and closest to america cause world is indeed little ball of yarn
