This is the second part of Caravaneer. The game is a fusion between an RPG with turn based battles and an economics simulator. You find yourself in a post-apocalyptic desert. Your goal is to survive and to try and gain enough power to complete your mission. There are different ways to achieve this, but the most straightforward one consists in transporting goods between settlements. Buy stuff where it’s cheap and sell it where it’s expensive. Then you can spend the money you earn on purchasing transport, hiring people or improving your battle gear.
