Be warned, I have yet to ever finish a legacy, though I would like to change this. Each child will be named after a sweet; be it a candy, dessert, or anything else sugary. I started out with a very beautiful sim, and I want to see how ugly I can make her descendants.
For anyone who actually read and was interested in my previous attempts at the legacy challenge, I didn't simply "give up". Rather I planned on re-creating my families after my first re-install, but never did. And by the second re-install I had forgotten all about them, and I lost their data. :\
