I am currently play-testing a variant of the Sims Legacy Challenge Created by Pinstar. The original rules for the challenge are found here http://www.simslegacychallenge.com/.
The basic concept is to follow Pinstar’s Rules for a Legacy Challenge extreme start but only to play until the death of the Founder. At the death of the founder score the challenge thus far. Then repeat. You must complete the extreme start with a founder with each starting aspiration. Your final score will be your average (mean) score across all aspirations.
