What I want is for the immigrant Sims to be the genetic offspring of my custom Sims, but I don’t want them to have their last names. I usually leave most options at their default. Setting the “Immigration Gauge” to something other than zero unlocks other options. The NRAAS wiki suggests using an immigration gauge of 1000 for Rapid Immigration. The first thing that you want to do here is to set the “ Immigration Gauge” to something other than zero. Then to get to the immigration options from town hall click NRAAS » Story Progression » General Options » Options: Lots » Options: Immigration/Emigration. From town hall click NRAAS » Story Progression and select “ Enable Progression”. To use Story Progression to rapidly immigrate Sims into your town you first need to enable it. These are Sims with various qualities (traits and looks) that I plucked out of previously played games and they are to become the ancestral parents of new Sims that are immigrated in my town. I think I have a total of 30 of these Sims (15 males and 15 females). In addition to the core families that I mentioned above I have a number of single Sim households in the Bin. There are a number of options to rapid immigration. The next step is use NRAAS Story Progression to rapidly immigrate as many households as you wish. You can do something like this or actually skip this step. These are families of six (parents, two boys, two girls). I have about six or seven households that I call my core families that always use when starting a new town. With this option you add Sims from the Bin to whatever house that you want. Now you want to turn on Free Real Estate by clicking on city hall and selecting NRAAS » Mover » Enable Free Real Estate. So, think of this Sim as only temporary and you can get rid of it later. This Sim is probably not going to be able to afford anything other than the cheapest house. Chose to create a new household or add a household from the library. Install the mods and then start a new game with the custom world. I use three NRAAS mods to do this: Mover, MasterController, and Story Progression. Let’s say you download a custom world from somewhere that does not have any Sims and you want to quickly create a thriving town. Populate a world with Sims from another world.

Re-populate a world that comes populated with Sims.

Described below are three methods for populating a Sims 3 world:
