Right now, I don’t think adding more diverse primitive weapons would make people use them. There are already a lot of rather primitive weapons UNUSED. First, you have to make room for these kind of weapons. Why should you craft a stone spear or some of that great diversity of swords and such, if you don’t go through that kind of progress slowly. it’s from bow to firearms right away. You would need to stretch that progression in order to make room. If that is made, you can add more divers options, but until then, that work would be for nothing.
