Space Freighter Example

This is a little space-freighter simulator, modeling an aspect of games like Elite, Escape Velocity, or Rebel Galaxy. There are three goods, which have prices that vary from one planet to another. Tribbles prices go like 1d6, Subspace Circuits prices go like 1d6 * 10, Stabilized Unobtanium prices go like 1d6 * 100. Fuel costs 5 everywhere in the galaxy. Unfortunately there is no control over where you get warped to, so if you don't like where you land, you may need to warp several times. Buy low and sell high to make enough revenue to cover your fuel costs.
