Really active NPCs

Other than in Sims 3, NPC are not really active. What I mean is, they do absolutely nothing, except they are on the same lot as the player. They don't work, eat, sleep and the like. You call an NPC at night by phone and they are angry, telling you, they are sleeping. If you move to their lot, they stand idle in front of their houses or watching TV! All things they do apparently are just fake. Especially in tha Royalty-Pack it would be advisable, to have them reasl active, because their is no fun in dynasties if they are just randomly calculated by the computer, without the sims doing anything.
