So it was spoken what kind of armor and what kind of armor improvements are possible. However, this brings up the important question of how much armor Slots are there? In addition, how much slots are necessary?

In addition, I wonder how much realism will there be? Have we a weird Skyrim world where everyone only wears one part of clothing? (And a bit underwear for the Teen rating)? Or have all Human like persons 37°C blood temperature and the environment is 37°C warm at every time, so that clothing was never invented? In almost all games, I know you have a provided set of clothes, which you cannot get rid of (exceptions Unepic and Skyrim). In Skyrim you are under the armor naked. I think this is strange. Think of a good oiled chain mail on the bare skin, what a mess. Alternatively, wander a day in new stiff leather armor; I can almost see the oppressed skin. Therefore, there is clearly a need for Clothing in general and worn under the armor.
This brings me to the next part. Taboos. In our world, the minimal clothing covers breasts and private parts. But have this to be so in P:E? Could it not be that the uncovered Hands or Elbows are Taboos?
