Each world will start off with some resources but they will not last for long, requiring you to produce what is needed, ship it all in, or even abandon some planets as you go. You will also have to adjust quickly to changed conditions not only on individual worlds, but deal with system-wide changes too. In the larger systems of Mittsu and Yottsu this gets extremely tricky. Which type of world it is and its distance from both your starbase and the enemy will determine how large a population you can sustain there, or whether or not you even can maintain a world at all.
