Ancient Megastructures

This is not so much a feature as it is a component of the landscape of either Droo, or any of the other planets. Ancient structures of a long lost and extinct sapient civilization (pyramids, temples, perhaps even ancient space ports, monuments, inscriptions with a long dead language). This could augment any future campaign mode with a lore component. Since the games object is exploration, this would add greatly to the games purpose. Perhaps even other planetary civilizations on Droo and Cylero, Nebra or Taurus. These structures would be more like surface textures on the planets rather than actual physical structures.
