I have a Sims 4 save full of characters from Supernatural and a separate save full of Glee characters... I mostly play rotation style in these saves or occasionally jump into a household I haven't played for a while seeing as their lives don't tend to progress much without me jumping in and I switch the ageing between long and off a lot too because I want people's kids to grow up etc. but I also don't want my favs to die.
Back in Sims 3 the save I mostly played in revolved around Kurt and Blaine from glee and I spent a good while filling their family trees as accurately as I could to the show, and then let story progression take over what happened to their extended family. That save eventually became too laggy to run on my computer though :(
