A legacy family? The idea was born on the official EA forums. The basic idea is to move a sim onto a large bare plot and build up his/her family fortune over 10 generations without using any cheats. The original idea started last September and had a lot of rules with points awarded for various goals achieved ... it was too restrictive to appeal to me but I was already something similar anyway.
The rules for the Legacy Challenge are outlined here http://forums.worldsims.org/showthread.php?t=3967 : a thread you'll find by scrolling down the General Discussion page (which is where you are right now!) just a little. I agree with Mirelly that the rules are restrctive - it's a fun idea for a style of gameplay and I've adopted the central tenants (10 generations, without moving out of the original house) for one of my favourite families, but I'm not all that bothered about the actual Challenge itself.
