Yes, I would love this so much! You've actually put into words exactly what I want and I really hope ghosts get further development like this at some point. I always picture ghosts to stick around due to 'unfinished business' (and this is often something they don't even know themselves and have to discover first before they can even go about trying to finish it) and I've always found it quite silly that ghost sims have the same needs as living sims. A hunger need makes sense for a sim that has died of hunger perhaps, but otherwise no. Also, what's up with ghost child sims still going to school? For all eternity? That is just cruel. I also really wish ghosts were only visible to vampires (and possibly other supernatural sims like werewolves) and sims with special psychic abilities - and perhaps visible to normal sims if the ghost chooses to appear or has earned the power/perk to do so. Some unique interactions between ghosts and vampires would be a nice feature too and way to combine packs. Ghosts generally could do with some more interactions and abilities. I'm also hoping for some new death/ghost types - because I'm evil like that. I just want ghosts to become a more distinct and fun life state to play and interact with. We need a fear emotion too. Ghosts making living sims tense just isn't the same.
