I'm new here and don't know where to put this so I'll just leave my suggestion here. If it's the wrong place, someone please move it to the right box, thank you.
One thing I love to do the most in a RPG is dress up my character. In TES, specially skyrim, there are many great looking armours but sadly, they are not always the best gear for my character. It would be great if in the new TES game (if there is any) Bethesda could make a cosmetic system. Let the players choose how their crafted armour would look like perhaps?
PS: Or even better, a mod of Skyrim for cosmetic just like Hearthfire for building house.
