Inplement Trade like Archeage. Where you have to craft and carry your package across zones on horseback/carriage. The farther zones you bring your package across, the more reward you will get.

It's very lively in Archeage when you had 10 people waiting for an airship carrying trade packs on horsebacks and then we all just chat on the airship during the journey. Or on ships/galleons that people built and drove across the seas to the other continents bringing our trade packs.
