Put a "Stop Generating Random Townies" Button in the settings

Some form of townie control would be good. What I would like to see is specific townies for each world. I do not enjoy seeing townies from Willow Creek in Granite Falls or San Myshuno. I mean if they're on vacation or out clubbing ok. But it is the same ones all the time and I find that really boring and lazy, I want to see, for the most part, fresh townies when I visit different places. Just not excess ones. An example of that would be High School. My played teens should take precedence over townie and game generated teens. But they don't. I will have the active teen I am playing go to school, and their friends, my other played teens in other households, will not be there. Instead all of these random teens show up and my teen sim doesn't get to go to school with their friend. I can go delete the random sims and it might work for a while but then something happens and my teen will be alone in school again. At any rate, we should be able to control townie regeneration and population to some degree and it would really make for a better game experience. 

Side note 223angela​ Edit your empty houses and change the bed count to zero and that will prevent sims from moving in unless you move them in. All of my worlds are empty houses other than my played households. I have not noticed this being detrimental to my game in any way. You'll still have to deal with townies though as it doesn't lessen them. They just end up being generated and "not in world".
