Cosmonautica is a trading and star ship management simulation game. You begin on a washed-up space cruiser. You will want to purchase cargo, travel to another location, and sell your cargo for a profit. As you build profit, you can buy better and/or bigger ships. When you get bigger ships, you can hire crew members, up to a total of eight, to help you run your ship. Once you hire crew members, you will want to keep them happy or they might rebel. As you travel the space ways, you will encounter other star ships. How you handle this is up to you. You can choose to be diplomatic or take a hostile route. Most ships will respond to diplomacy but some, pirates, for instance, may need to be fought.
