I found that you could very easily created a fairly plump female, or a very very heavy male. I think that like it's been said above, 90% of folks pick something in the middle, or some way they'd LIKE to look. And yeah, if the models get too wide then there are clipping issues. It's certainly possible to create a size 14-16 female.

Are the skin and hair colors just preset color sliders, or do they include an rgb scale slider? I think that'd be pretty cool. I like using specific named colors.

Because no one likes their in-game character looking like their real life selves. Also, not that many are fans of the "biggest-strongest" male fetish.
