I rolled for the occupations of their parents, whether their parents were alive, their number of siblings, and 3 things off a d% that happened to them as a child. 4/6 actually requested an extra d% roll.
They rolled their own stats, but did not put the highest stat in their "power" score. For the most part, it didn't matter, since it was a difference of 1 point, but it does provide great variety!
I've already gotten two private emails from players saying how much they loved the way it was done.
Excellent. Thank you everyone. Special thanks to the person who suggested not putting the highest stat in the prime requisite.
