This is a new version of a mod concept originally by SHUSHU which I enjoyed using in my own game and wanted to maintain as the game was updated. In a general sense, this mod controls which Sims appear as walkbys, service Sims, and customers on community lots so that primarily local Sims show up. No longer will Eliza Pancakes haunt every lot in the game. Every World in the game even gets its own set of townies. Read on for more details.

Local Sims

Home Regions changes the game so that NPCs, such as vendors or Sims walking in the background, will be Sims living in that local World (i.e. only Willow Creek residents will show up at Willow Creek venues, only Sims that live in Oasis Springs will show up in Oasis Springs). Sims you specifically invite via phone, club event, or group system are exempt, as are certain roles where it is necessary for gameplay.

If there are not enough Sims in the World to fill a necessary role, the game will automatically generate homeless Sims who live in that World. Sims generated this way will remember their World, and will keep showing up there.

Note: Homeless sims will not get generated infinitely, only enough to satisfy the game's requirements for NPCs, but this mod will very likely increase the population in your save file.

Smarter Sim Spawning

Home Regions changes several game filters so that the NPCs the game chooses make more sense, even beyond what World they come from. College parties won't be full of Elders, Sims traversing the Magic Realm will actually be Spellcasters, etc.

Home Regions also fixes an issue where townies would all be assigned to a small number of Worlds. In an unmodded game, nearly all NPCs end up living in San Myshuno, Sulani, and Mt. Komorebi. With Home Regions installed, Sims will generate evenly across all Worlds.
