The cool thing about the Traveller system is one is not necessarily bound to the official background. Unlike many rule sets, the TNE version of Traveller can be used to replicate every genre from stone age to god-like super tech.
The world I'm building is a low tech world terraformed about 65,000 years before. In the intevening millennia the original civilization has long since gone, as have numerous civilization since. At least one ice-age has scoured the surface of the planet in that time too. The current inhabitants have clawed their way back to the pre-Industrial/Industrial tech levels and have no knowledge of that long-ago ancient civilization, although that will probably change in the very near future...
The big inspiration for the look and feel of this world has been all those Japanese anime steampunk /steam fantasy movies I've been renting the last couple of years (Howl's Moving Castle, Castle in the Sky, Steamboy, etc.). Also, I wanted to have a "legendary" past for the world along the lines of Atlantis (and the Conan stories).
This is the part of Traveller I've always loved -- world building. The equipment lists invariably flow from the world's background...
