Trade Away.
In Trade Away you are a traveling salesman in the 1600's. You travel from town to town buying and selling your merchandise. What you sell is up to you, you buy what you choose and sell what you choose. Prices differ from town to town so having a good spread of inventory is a good idea. Some roads are unsafe and you may look to hire on a guard if you think it's worth the coin.
Trade Away is a caravan RPG. You manage a traveling caravan starting with a simple wagon and ox. You set out into the world to buy sell and trade goods. You need to manage your health and supplies to stay alive. The things you bull see and trade have different prices around the country. The only way to know what things will be worth in another town is to go there, however you can gain some information about the surrounding towns by talking to locals at the bar. The aim of the game is to have the biggest caravan possible.
