Everything else requires Refining Resources to produce. The economy is an important aspect to the games - the only wares that are generated without resources are energy cells, and ships at shipyards note Ships built by the player, however, have resource and time requirements. Player-owned ships can be commanded to perform tasks, such as patrolling, exploring, or trading. There are many classes of ships - fighters, carriers, corvettes, bombers, freighters, etc - and each race has their own ship set with their own unique advantages and disadvantages. The series from X-Tension and beyond - with a notable exception in Rebirth, which caused a massive Broken Base - allows the player to pilot almost anything they can see, from tiny scout ships to five kilometer long destroyers and carriers.
