In Orbital Trader each of the planets can only build one good type. This is where you and your only interplanetary spaceship in the system come in to make a killing profit.
Getting rich is easier than ever in Orbital Trader. Buying low and selling high is guaranteed - since each planet will only sell the one good it is producing and will pay well for all the others.
Getting rich fast is where the challenge is at. You'll have to navigate with much skill so you can visit as many planets as possible in the shortest amount of time. And if you think that only the expensive goods will be worth trading, think again. Maybe you won't get rich by trading food and medicine, but if you do the planetary populations will grow fast and you'll watch your profits explode.
Don't think trading is all there is to the game. You'll have to upgrade your ship until it becomes a huge transport vessel. You'll race to complete very profitable special transport missions. You'll have to stop a deadly virus from ravaging the system. You'll need to make the best of the special events that occur on planets:
Sell enough goods to stop the crysis or take advantage of the high prices?
Buy as many goods as you can for a cheap price
Perhaps you like to be an arms dealer?
Travel rapidly through rifts in the space time continuum
Earn enough money and you'll be able to invest in the planets. The choice of what should be built is yours:
These will create and sell goods on the local market (you keep the profits)
They cost a fortune but they speed you up so you can trade more
They teach the population about why they should buy art from you
Solve the overpopulation problem
If you don't feel like taking risks, just lend money to the government
