@Tuoni One of the things you may have missed in previous articles is that the game is in need of some Gold Sinks. Travel, like to other Continents/Worlds is one of the planned Gold Sinks to keep Gold relevant in Fractured.
It has been argued back and forth about how they maintain the valuation of Gold when there aren't enough gold sinks in the system to create a pressing need. Like in any market, you create value by rarifying some items on the market itself. If you have to pay a substantial gold price to move certain materials from one Continent/World to another in order to complete certain craft recipes, the results of said recipes will thus have a far greater value to compensate for the cost to attain/gather and thus it will stimulate and help maintain the Player Driven Economy that is a cornerstone of Fractured's design.
