Weapons have different effects, like armor-penetrating armors, daggers that slip in the chinks of the armor, and maces that smash bones, ignoring arrows. The more punishment your weapons and armor receive, the more they get destroyed and become less effective. So, I was wondering why no game that i know of has ever realisticly approached armor and weapons.
Your armor is bloodied and destroyed, your blade chipped by smashing metal on metal and both are in need of some TLC. The brave orc drops his warhammer as an arrow sticks out of his eye socket. You ready your bow, and aim for his naked, defensless head. Luckily, Lydia is weilding a mace, and she smashes his helmet, leaving his head exposed.
You get back on your feet and hit him on the chestplate, but your blade bounces of his heavy armor.
You get the first hit, but the orc retataliates with a massive blow to the chest, denting and smashing your armor. Imagine you wearing a nice set of armor, freshly crafted, and proudly going into battle against a warhammer weilding orc.
