It's very hard to choose just one. I want a little bit for everyone that is not a young adult.
I would like improvements for toddlers and children. They need more to do and not left out in so many new gameplay (why are bikes, boats, magic,... only for teens and up) . And some gameplay differences between young adults, adults and elders would be welcome, they are far too much alike at the moment.
For babies, I want them to be released from their cribs and adults being able to carry them around.
The only ones not high on my list are teens, actually. Lol :) . But they should have been an option for this question to be complete.
