I suppose I could, but I prefer generating the lot - it's more consistent and it avoids the sort of sillyness I mentioned earlier. Besides, some of the descriptions can already get pretty long.

But if it's an alternative form they may end up using it more frequently than their "original" shape. This is very much the case in my mud, for example, where many characters are built around a specific shapechanging ability.

I allow players to select choices about their appearance as well, but I don't think self-policing would work very well for me.
