Gameplay is simple and a joystick should really be used due to the steadiness needed to dock at the different space stations. Game setup and configuration uses conventional Windows dialog boxes and is about as simple as it gets. While this is relatively easy to do, the results aren't that impressive, since the game's external view commands give you very little control over zoom and angle, and the actual image is extremely small. Furthermore, without multiplayer support, there's no one else around to admire your handiwork. BtF trading model is based on simple supply and demand.
Every factory produces a primary product that another factory is likely to require.
For example, a Solar Powerplant makes energy cells, which sell at an average price of 10 credits. Most factories that need energy cells will offer between 15-25 credits. Every Trading Station sells Cargo Space Extensions. Increasing your cargo bay will help make more money early on, but you'll need to buy a factory for the really big profits. Locate the transport, fly toward it and communicate with it.
