I love playing the premade sims. They all have stories that they start out with and then I get to expand upon them. I like what you've done with everyone! Especially Agnes. I've always had a soft spot for her because her story is so sad. I'm looking forward to seeing what happens now that she's seen Erik's ghost! Or are you just doing one entry for each sim?
I still prefer 3 over 4 too. I feel like I'm more in control of my game and I miss being able to change the colors of all the furniture and I just think the sims look better too. (love sims 4's building tools though)
