Well,
I very much enjoyed the Halloween themed video! These project updates really make me glad I was a Kickstarter member.
On to the Armor topic.....I think some science background might help with reasons to wear different types of armor. I'm assuming that there will be various types of elemental damage in the game. Fire, Ice, Electrical, Poison, Acid that sort of thing. I think persons in heavy plate armor would be at a severe disadvantage to the conductivity of metal. Heat, cold, electricity: those things could affect the wearer in more adverse ways. It could be assumed that natural armors (especially certain hide armors) would lend more insulative effects, or at least the possibility thereof. While the converse could be thought of for permeable types of damage like poison and acid. Heavy plate armors would not be microscopically porous like natural "skin" types of armors. Damage types that were say lipid soluble would be quite harmful to wearers of leathers.
Just some thoughts to throw around. Whatever is in the game, just have it make SENSE. The game mechanics are very important, but give me real world reasons and in game lore/traditions for what I might want to wear to protect my precious innards!
