@Simburian It would be better if Sims ghosts had their own 'lore' - sometimes it works to implement a lot of different ideas, but it would get too complicated with ghosts. It 's better to try to simplify it, and make the tools and the gameplay as simple and powerful as possible - that way simmers could make their own stories. If I made this features, I would implement certain option settings that could help, like decide what sims that can see ghosts, if ghosts are all the same age etc. You could use skills and/or traits and even objects to modify the gameplay. It's all about imagination and simplifying game tools.
