While not my thing in general, i Love how Ryuutama managed to reduce all weapon categories into six. I think its on the rules that Maces/Hammers go with Axes into STR based weapons.

It might make not much sense from a Weapons VS Armor paradigm, but it works to give each weapon an utility and a personality to their bearer; as at the start you must choose to expertise in one of those. I think it does a great job for its genre.

I think i am doing the same for my JRPG inspired game; though probably changing the categories a bit: Light blades seems a little pointless, when a knife can actually go under the "improvised weapon" rules. Maybe I could make room for a split on polearms, in order to make room for one handed spears or separating longspears from greataxes.
