Hmm...
I feel like there is some kind of chemistry going.
You know when you are going to a new lot and one sim runs up to talk to your played sim. I play rotational and this week I have had a few played sims who met a sim they have great chemistry with this way.
My main sim’s sister. I played her a day to set up some skills, a job and other things. Swing by the Art Center. One male sim enters the lot and head straight for her. Turns out that they have great chemistry. The green bar and the pink bar just jump up.
My elder spellcaster in my main household went to the bar in Glimmerbrook for lunch. The sage Faba enters the lot and heads straight for him. They had great chemistry as well. In this case I knew about the great chemistry between these two sims since an earlier save but it was still fun to see her enter the lot and head for him. Will let them have a romance in another save.
Hope we will have a Game Pack or Expansion that builds on this. With fun dating and some kind of matchmaking.
