The Sims 3 Nanny Career
I'd really like to have a career for 'poor Sims', so that even when they reach the top they don't get too much, this way it would make sense to marry a poor Sim to a rich one:D. Unfortunately there are no truly bad jobs in Sims 2 with small pay. As for a nanny career, there is another upload of all the NPC careers on this site. Ie someone's.
Lifetime Rewards Long time fans and Sims gamers will be familiar with the concept of Lifetime Rewards because there was a similar system in The Sims 2 -- but in that system the only way to obtain points to bank was to successfully complete the various ambitions and goals of your Sims. Doing so banked points in the family bank and allowed the player to purchase objects that were very useful, like the Money Tree or a dispenser that held the Elixir of Life that could literally take years off of your Sim and extend their life in whatever stage that they were in when they drank it. The system that is in The Sims 3 is a little different but basically the same, though in place of mythic objects your Sims instead can obtain special abilities and devices, kit that makes their lives better and abilities that do the same! The trick to obtaining them is to bank points, and the trick to doing that is to complete goals, and keep your Sims in a perpetually great mood! -- Increasing Your Point Bank -- If you played the previous games you may have an imperfect understanding of the Happiness Points system and Lifetime Rewards as they exist here -- previously you needed to complete goals and challenges in order to increase your bank to buy rewards -- and you can still do that and you should, but in addition you also gain bank whenever your Sim's mood meter is in the upper bubble and your Sim is elated, as when that condition is met the bank is metered and constantly increasing, even when your Sims are sleeping! The trick to maintaining heightened mood is in maintaining your Sim moodlets -- basically that means paying attention to things like Hunger, Bladder, Energy, Social, Hygiene, and Fun, and keeping them in the green as much as possible! Obviously you have limited control over Energy, but the others you have near complete control over, and so you should exercise it.
Maintaining the majority of the moodlets in the green and not allowing any to ever go red (and trying to avoid any going yellow) is the best path towards keeping your Sim's overall mood in the upper bubble and thus continuously gaining points in your bank. -- Interest-based Goals -- As your Sim develops its own interests you will notice that the goals that begin to pop-up that you can accept relate to those interests. For example playing Chess will prompt logic-based goals as well as cause logic-based opportunities to appear every now and then.
