Originally posted by geoschmo:
Early space flight primitive races. Capable of building sattelites and small orbital bases. Could even give them primitive missle and particle weapon technology for defensive purposes.

You could do all:

Dirt Races
Steam Races
Space Races

But each would require their own Racial Tech tree, to keep them separate.

Or perhaps the Dirt Races could move up to Space Races. This could be very amusing in a Huge (255) map with only a half dozen players.
