Even so, it is a sensible precaution to back up the world before attempting this. Suffice to say, worlds populated with this method should carry warnings, but appear to be safe if certain rules are followed. These testers have now maintained working worlds across four or five generations without any corruption that is apparent to end users. However, creators should bear in mind the pool of testers has been small and largely non-technical. Testing to date demonstrates that these Sims will be installed with the world file, and will act just as the premade Sims in Sunset Valley or Twinbrook. It is possible, using a combination of mods and EA debug commands, to add Sims to custom worlds using Edit-In-Game in the Create-A-World tool (CAW). Please check out the discussion page for less substantiated research and areas to look into.

You can count on spending several hours doing this, but it is well worth the effort. So 50 houses supports a population of 150 sims.

I sort of assume that the typical house will house 3 sims on the average. You really only need 50 to 60 for a well populated world. By the way, last time I looked, there were over 300,000 homes available for download at various sites. Then you can move them into the homes in your neighborhood. In any case there are thousands and thousands of premade sims ready to be downloaded and installed. I am assuming people are uploading their sims because they want them to be used. You can find sims here, on the exchange, at TSR or through other sites like the My Sims 3 blog.

Personally, I really don't want to be bothered making 100 or more sims, so I filch other sims. Plan on adding between 30 and 100 sims to your world. This means, you usually need to kickstart the process. Waiting for the story progression to fill up your world does not work if you want to play a social game. But your young adult sims may very well be elders by the time their are suitable spouses for them. The various story progressions will eventually fill up your worlds. But those are the exceptions rather than the rule.

It's not universal, and there are a FEW populated player created worlds. One of the weaknesses of most player created worlds is they come unpopulated.
