This game features a realistically generated galaxy in which you must find a habitable planet.
Learn about astrophysics as you find the best strategy to find habitable planets quickly. Your ship will run out of fuel, or water if you don't look in the right places to replenish them. Without fuel your ship won't make it, without water your colonists won't either!
All planets are not created equal, don't be afraid to look around for a better candidate if you want to get a better score. Think about what earth is like when you choose to colonise. It's a one way trip, your ship can't take off again once it's landed on a planet!
