I saw that image almost the first day i visited this site and assumed it was concept although now that its enlarged i do see some more info
that ship in the bottom right between Terran's and economics looks like a carrier from starcraft i think
but there's some kind of gas nebula on the bottom right corner that seems to be limiting the influence range from both the Terran and Alterran's.
as for the "economics star-base" it looks like its linked to the asteroid belt on the left in some form possibly a mining colony or using the asteroids to make components
while speaking of the asteroid belt the asteroid top right in that belt is highlighted red some kind of danger? its been identified as being on a collision course with earth?
