ill talk about the economic side of the game (the long run piece) a little later but basically planets will be in the game, and will be where you do most of your industry. in addition, planets will be able to do certain tasks for you (mine, build ships, etc) for a price. The price will depend on the planets relative abundance of the three raw materials of the game (metals, minerals, and oil). ships cost are based on what components make them up (chassis, armor, tech, etc) with a default price given to every component. Once the real game starts, it is very unlikely a ship will cost what it costs in this version of the game, because 'price' will be dependent on the planet doing the building, or the cost of the materials, plus any labor costs from the planet (if you build it yourself, you dont have to pay labor, but you do have to amass the materials but mining/producing them or buying them)
