I was thinking since leaf has everything, other villages should have other shops as well. which will lead to more exploration. Maybe have weapon shops in each village with specific themed weapons for each of them and possible new effects. An example for stone village could be a metal hammer and a crystal mace. Some type of water-themed swords for mist. Just having more variety and new effects could definitely be something cool players could look forwards to. Armor/ clothing shops could also be something such as flaks (for when you are jounin) and specific hats and other cosmetics that are village locked.
