Trishasmom and Trifle, those are great ideas. The sunsets, the outings, etc.
As for the holidays, maybe they should program something in the beginning where you can choose what type of family you'd like to have - what holidays to celebrate, etc. Change of seasons would be nice as well.
I love the idea of interacting with other families and famil members. What about being able to interact with the other families your computer is managing? I would like that as well.
The other thing I noticed are the jokes and charades. They tell jokes to an empty room and play charades by themselves! That might be something to change as well.
