Well, every time I create a male character, I get board with him before he reaches lvl 10.
If you're going to spend a lot of time working on a character, they should be nice to look at (especially from behind), and guys just aren't. You can make em look cool, but that takes work. But girls have it all built in, heh.
Oh and there's also a better hair selection for female characters.
Anyway, when it comes to the face, I always spend a lot of time on it, and frequently go back to it over and over again, tweaking it here and there, until I'm convinced that there's no other way I can possibly make it look any better... And then a week later I change it again.
Needless to say, I've gotten pretty good with the face editor from the frequent use, but that's beside the point.
