You can make 3 improvements to TS4 to perfect it. What would you improve?

3 improvements, eh?

1. For starters, I'd scrap S4 and re-visit what made the game so appealing in the first place.
2. I'd stop worrying about being politically correct and non-offensive to the over-sensitive.
3. I'd re-introduce a world creator and just have fun with a real parody on life (both the good and the bad).
