Thank you so much for your cute lot - but even more for the information about the Decades Challenge 1890. This sound really like a challenge. I read the information about the whole thing by using your link, and I will try to manage it. I just found here at MTS the technophobe trait (https://modthesims.info/d/628581/new-hobby-traits.html), which may be helpful at the beginning of the game. First of all I'll create a family of two old people and two young adults, and then I'll place them in your house, preferably in Willow Creek. The only problem I see are the many modern fashioned sims walking around, who will not fit into the time of 1890 or a little later. Do you have any idea how to treat this problem?

@ BrittaMA: "Do you have any idea how to treat this problem?"

Yes I would like to know too If you have Newcrest you can start your challenge there, but you will still have the probelm with the NPC visitors.

Hello!! Thank you!!
So, I don't know if they say something about this in the file I linked... but I guess one option is to place the house near the woods... like I did (in Brindleton Bay or Windenburg), I mean, away from city, so you'll not have much contact with the modern sims/objects... at least for the first two decades.
I'm going to search... if I find something, I'll PM you

That's exactly what I thought... to place the house sort of in the middle of nowhere whilst living in the firts two or three decades
