The game is fairly simple. It starts out in the past with a planet escaping a Super Nova, sent colony ships to yellow dwarf stars and new civilizations were started. Fast forward 1,000 years, and knowledge of where these colonies ended up is a mystery.
Your mission is to find all of the colonies and set up trading and passenger traffic between them. A winning condition is when you can transport passengers from one star system to another, within a specified time frame.
