Charactersliders? Stuff like, the lenght, with & seize of
° limbs & boobs etc.?

Might be worth a shot although I am afraid that some people create monstrositys and ruin some forms of multiplayer & co-op with it. ^^;

The Drow definitely need it. It is canon lore that Drow females are actually taller than their male counterparts.
And that they are probably a little taller than most other Women from other races as well.
Not that heavy detail - but it is a detail.

Also I like it in general if you can create stuff like "a teenager" or very tall member of a certain species with such sliders.
Customization is everything after all nowadays and every game that wants to capture as many players as possible, should have it.
