It's absolutely not for me, that's for sure. I don't like the focus on the emotions, I don't like emotions being part of gameplay. I played Sims 2 last week and at one point some townie visited my sims. She apparently had a bad temper, because even though she rang our door, as soon as my sim started talking friendly to her, she behaved nasty. My sim didn't like that, so we decided to teach her a lesson :mrgreen: by pulling some pranks (throw a water balloon, giving her a buzz handshake) and the atmosphere reached below sea level pretty fast :D So in the end they were really mad at each other, pushing each other and it ended by a threat of the other sim she would bad-mouth my sim in public. My sim apologized and later the other sim phoned her twice to have a chat, clearly to improve the relationship again because it did.
Now, that's emotions for me. I could clearly see what they were feeling, I had some choices how to treat the quarrel and that's more than enough for me. The pushing was utterly funny to watch by the way.
I don't need my game to tell me with little jingles (they irritate me, don't know why) and a pic of my sim at the bottom showing the mood they're having how they feel. To me that feels like I'm a little kid learning about emotions.

I also don't like it they can end up having moods by doing totally unrelated things (like watching a painting or taking a shower). The reason I had fun with my quarreling sim, was that I could see it building up in a natural way. When people behave unpleasantly we get mad at them. And afterwards we can make it worse (by fighting) or better (by apologizing). I can relate to that, that's what emotions are about for me. I also prefer that though my sim was angry with that woman, she was normal and loving to her own husband. In Sims 4 when something makes them angry, they're angry in every situation following. When they are flirty they flirt with anyone. Not just with that one particular sim.
