I want a pack that focuses purely on the Sims themselves, something that adds a boat load of new in-depth hobbies, activities, traits, developmental traits like from Parenthood, and so on, so I guess something like Parenthood, but with the individual Sims and their various life stages being the focus as opposed to parenting and family dynamics, a pack like this would make a good opportunity to essentially 'overhaul' the currently existing traits and emotions system that some wish for.
