i am currently working on a rpg game based on skills and the issue i am currently struggling with is how armor should work, i would like to have every metal (full plate, half plate, chainmail, scale mail) have some use even if there is a stronger metal. gold is physically weak but could have a much higher enchantment modifier? copper is weaker than iron but may be more magically resistant? or should i disregard normal metals and create brand new ones that can be crafted like adding a metal and a elemental flux (fire) creating a fire resistant mid strength metal? any ideas or experience with this?
