Since the Chage from Whims to Wants I have tried 2 families. I deleted the first because of the incest bug. I have not had 1 single want that was in any way related to the sim's aspiration, regardless of what that Aspiration is. I have tried the Wealth and Mansions, Spell caster, Beach life, Artist, even the children's aspirations do not relate to their wants. The reset Wants potion does little to change the wants they just recycle other old wants. With only 3 primary Traits there seems to be very little want variation. With Children and Teens, you have even fewer. It has become painfully clear that Likes and the 3 primary traits are what drives wants. Since there are missing activities, it is hard to get a sim to want to do their Lifelong Aspiration.
