Why? Mostly out of boredom.
I don't have any hacks or mods in my game because I have not figured out how to download them on a Mac so I was thrilled when Generations allowed me to complete edit premade sims in CAS.

When I first found out this feature I decided to edit a family that was already made. The Bunch's seemed like the perfect specimens. I basically edited their facial features to make them more attractive but without changing them completely.

Lisa Bunch had a rather large nose, so I kept it the same size but now you can actually look at her without that feeling of nausea. Same with the other's.

I could have made Jack thinner and more muscular with the sliders but I made him work out on his own. I did give him more muscle tone, though.

I'm yet to work on Judy, I've been having Jack train her so she loses all that weight. Then I'll work on her.

I was too lazy to work on Arlo, so I sent him off to boarding school. Actually, I did that because I hate taking care of a bunch of children at once.

Anywho, I'm going to make the Bunch's into the perfect family.
I'll try to get some pictures up.
