Ruins?

[Nanophreak]

I know it has probably been talked about before.. but what about ruins? If anyone took the time to read the owner's manual it states "In existence for over a thousand years, the Terran Republic was the sole governing power." Now if they had really been around for 1000+ years, where are some ruins/buildings and stuff? I know to put stuff like that in, would probably make some people's fps drop sharply, but it was just a thought.
