This is very cool if you have a super Sim you want to be able to try different traits with. Age Up Cheat: Trigger Age Transition This can make a Sim age to the next life cycle, which follows this pattern: Baby, Toddler, Child, Teen, Young Adult, Adult, Elder. The only way to Age Sims down is to use Young Again, a lifetime reward or chemistry potion from The Sims 3 Generations expansion.
It'll also help with the Super Popular Lifetime Wish and the Charisma Challenges.
Career Promotion Cheat You can change your Sim's current job and even give them a promotion to the top level in that career track.
It is a one-time boost unlike Make Needs Static, below.
It does not, however, affect guests at parties or other NPCs on the lot - that means Sims who have been affected by ageuptonpc will not be affected either.
Thanks to Neveryon for confirming how this one works - I originally thought it would affect all on the lot.
Make All Happy is Unlimited Needs Cheat: Make Needs Static When you use this, your Sim's needs will be locked.
Check out the different special abilities your Sim earns for reaching the top spot.
Look to the Career Guide for information on the perks your Sims gain as they climb to the top of each career ladder.
