The goal of the game is very simmular to the goal of Minecraft. Well yeah, No Man's Sky is basically space-Minecraft with more lore. So the goal of the game is to farm and collect resources to sell them. You can buy spaceships, frighters and more recources with that money. You make your way through the unlimited worlds of space.
