I am hoping for a personality overhaul or an attraction system of some sort. I don't really use the baby life stage as much, being a story-teller, so I don't quite care about that aspect. However, something to do with sim behavior would be intensely interesting. However, I wouldn't be opposed to adding in the sims' ability to injure themselves. I know it's not something too boring though, because Pixelade is super hyped, and we have similar styles. I know it's not cars, and that has already be debunked, but also because I don't see the point regarding The Sims 4 closed world set-up.
