While it didn't go that way, the AI is vastly improved and sims will actually take care of their basic needs themselves unless you prevent them too, so you can basically go as hands-on or hands-off as you please, since you can focus on the wishes of your sims and the stories, rather than worrying if that one sim you're not controlling now is gonna piss himself in the living room. The added RPG-like elements are also a huge improvement. Assigning the sims traits is kind of like deciding on their attributes when creating the character, and even sims run by the AI will perform based on those traits. Evil sims will steal candy from babies on their own, for example.
