I like the ghosts in the Sims 4, however, they're only really useful if you want to play as them and wouldn't be considered very scary at all. As far as I know, ghosts don't generally give your sims ...
I 100% support this thread! Ghosts in TS2 were so much cooler and scarier. I wish ghosts in TS2 would reenact their death, as an autonomous interaction. I also wish ghosts could make objects work by themselves instead of just making them float or shake like on TS2. And I wish the ghost scare was a negative towards relationships instead of positive.
It would also be cool if ghosts got angry when their spouse remarries, or their personal objects are sold, etc like on TS2.
