I recently took a look at a game called Archeage, which has pvp loot system blah blah no one cares.
But i noticed a really interesting mechanic the game uses when you have lootable, crafted crafting materials they call “trade packs”. A huge backpack-like think that shows off that you have some resources on you. This is what rust needs. Its funny to think a naked man can run around with 1000 wood, but since they can, and you cant actually notice the difference between an empty and a full inventory, KOS will always be a problem. Its not becouse of BM, i wouldn’t kill a naked guy with his dong hanging out if i could identify he has nothing, but i would if i could visually see that he has stuff in his inventory.
