I think there should be a new building, I think it should be called “Trading Post?”
*Can Trade Resources Like Wood to Metal, Metal to Wood with a fair conversion.
*Can Trade items to another item with the same grade (ex. Ancient Tablet to Mechanical Claw [Rare], Daisy to Mysterious Feather [Rare], Diamond to Ruby [Gems] for a fair conversion, Etc.
This is just a suggestion though… But I think it i will just edit this topic and add more Buildings! Chow!!!
