Whilst I like the idea of being able to take on deformities and generally ugly my characters up as much as possible, I don't think anything this major should be in. Makes for a lot of extra work. It's essentially adding twice as many races, each with a unique skeleton, animation, mesh, texture, and sets of clothing and armour.. No ta'. Something that changes the walking, running, and idle animations like a limp, or gout, or clubfoot or something.. that'd be fine, and not quite as difficult. Unless they force you to take negative "perks", however (which I'd love), I can't see the point of adding such. Why would they, when most of us wouldn't even use it?

this would be one of the more troll-rific things that you can do, simply because the hunchback of notre dame doesn't sound like the guy to save the world from the all-consuming wrath of the dragons.

Would be nice to have hunchbacks - not of the extent the OP is suggesting - but more of a slight hunch, would make the beggars seem more believable.
"I’m so poor, hungry and destitute; but at least I can still rock six-pack abs"

if there are body customisations like height and girth, it shouldn't be that much trouble to give options to make the character slouch forward a little.

I think it could really add something to a doddering old wizard, or even a desperate thief.

I'm not I'd rather have crossbows in.

So happy you wrote *couldn't* care less. As opposed to how some people write it, 'could' care less.

But yes, couldn't care less.
