I'm actually going to have to side with Vance here. I feel like all of that information could be greatly useful in dozens of nonverbal ways. Racism in a roleplay, which does exist. Maybe psychology. It doesn't even have to be combat. What if a particular woman in a roleplay was attracted to taller men? What if several facts like that just synced up on character sheets? There could be an unspoken level of physical attraction between characters, all of which accomplished by factors such as skin tone, height, hair-length, etc.

Now, I rarely, rarely ever see any of that in practice. Unless you're in the Advanced of the Advanced or maybe a Slice of Life-esque roleplay, I don't see a purpose for that level of detail. But, I could easily see how absurdly specific information could be useful. I mean, think about this: what do you like about the opposite sex or even the same sex (I'm not judging. Maybe taping, but not judging)? How often do you think some of those traits even show up on a character sheet?
