I have no idea on how possible such a mod would be, but would it be possible to make a flying mod? When I saw those graphics, I had this mad vision of flying around on something and exploring...
But flying, not no-clipping.
D'you think it's possible to do? Flying on a flying monster or something?
Because that would be heavenly, I think. Horses are all fine and good, but flying'd be just amazing.
It would be kl if someone modelled a flying unicorn with white wings, or a flying shadowmere with black wings (evil or good, whatever you want). That way you could fly around the landscape in joyful splendor.
