Okay, I'm not quite sure where to begin with this post, but I'll just start.
One staple in many Elder Scrolls games that garners huge support is modding, and Zenimax and Bethesda know that people mod the hell out of their games. That's why they're going to allow UI mod support.
But what about altering how our character or clothes look?
It doesn't affect others, and it only enhances our gameplay to make it more enjoyable. nvde mods, character beautification mods, generally just mods to make characters look better or more realistic would be in high demand. So, since it gives no advantage whatsoever and it would only need to be on the players computer, think that they'll allow these mods too?
