What small things do you wish you could tweak in the game?

I agree with a lot of what has already been said. Additionally, I'd like:

- The ability to buy a second home. Rentals are nice, but sims can't normally work or go to school while on vacation.
- A real estate system where sims can buy community lots.
- More simple reactions. Sims should react when another sim is moving out or when a child gets an A.
