You have traveled to the largest sea ports in the world, and you have arrived at the port of Rotterdam, where you can trade with the best traders. It is a port where the players can compete with each other, and where you can find the best items in the world. The game is based on a simple concept: You will compete with other players for the items that are in the containers, which will be sent to the appraiser. If you win, you will be the owner of the container, and you can then trade the items with other players.
