Ghosts do need an update, it doesn't make sense that they need to eat or use the bathroom. They don't have physical bodies!
Could be interesting though if ghosts that died of starvation would occasionally get a hunger moodlet that would only be satisfied by eating. But the food would just go right through them and they may get a sad/angry/embarrassed moodlet afterwards.
Would also be nice if kids and teens could register themselves as dead at their school. There's really no need for an education when you never grows up and can't have a job!
Also aliens should have the ability to remove their disguise completely, the same way vampires can remove their dark form.
Would also like for merchildren to have tails in water, since they can swim just as much as teen-elder sims can.
