Lifetime want

Introduced in The Sims 2 University, a Sim's Lifetime Want (or LTW) is a special want that represents the Sim's ultimate goal or something that would make his or her life "complete".

Lifetime Wants tend to be very difficult to complete during a Sim's natural lifetime. When one is fulfilled, a Sim will receive a very large amount of aspiration and influence points. Once a Sim has fulfilled a Lifetime Want, they will receive another Lifetime Want.

Without the FreeTime expansion pack, Sims who achieved a Lifetime Want will also receive a permanently platinum Aspiration bar. This in turn causes that Sim to have a permanently platinum mood and reach perma-platinum status.

If the FreeTime expansion pack has been added, the first Lifetime Want realized by a Sim will contribute to that Sim's Lifetime Aspiration score, but will not create perma-plat status unless the Sim is close to maxing out his or her Lifetime Aspiration Meter.

= Lifetime Wants by Aspiration = A Sim's Lifetime Want is based on their aspiration. For example, a Sim with the Family aspiration will tend to have a family-related LTW, such as having a specific number of children or grandchildren, whereas a Sim with the Fortune aspiration will tend to want to earn a certain amount of money during his or her lifetime.

Player Tips & Tricks

 * Theoretically, it is possible to have any individual Sim complete all of the Lifetime Wants without breaking the rules of the game, though this would take a fair amount of effort and liberal use of Aspiration rewards.
 * When a child Sim grows up, you have to pick their Aspiration, but it won't show you their Lifetime Want right away. You have to save, go to the neighborhood and return to that household to be able to see it. The neat thing is that if you don't like the Lifetime Want, you can go right back to the neighborhood (without saving) and when you return to the household the Lifetime Want will be different. This is a cheat-free way to pick Lifetime Wants. (Disclaimer: This has not been rigorously tested. I have Nightlife and University)
