Do you guys think this would be possible?

Kinda like "The Sims Medieval"?

I have a phone overhaul for historical simmers coming later that uses a letter +UI changes but it won't be anytime soon since I'm catching up on other projects (I also have a newspaper mod in the works), sorry. D: In the meantime though there are mods that stop sims from messing with phones, phone texts, and there's one that actually replaces the phone animation to a listen one so that sims don't grab their phones. There's a post here listing some of them: https://sims4historicalhq.tumblr.com/post/621831994349879296/de-modernize-your-gameplay

For the TV's and computers there are typewriters, sewing machines, etc. versions that you can use instead (usually under the word "functional __") but there isn't anything that overrides every single object. These objects are just new ones you place down like any other TV or computer. Here is one: https://modthesims.info/d/623802/sims2-freetime-sewing-for-sims4.html

For anyone curious: I found a CC computer reskinned to be a book

Your sim skill types like they are on the computer but that's whatever. Nothing for the phones so I'll just download the nonautonomous phone interactions and use my imagination for the pop-ups (and turn my phone on silent depending on how far back we're going lol)

There used to be a loom that replaced the computer, too. Haven't used it in ages, don't even know if its still around.
