Who wrote those marketing texts? Especially the Blacktron II one not only sounds bad, it also doesn't contain any real impulses for imagination.
The interesting part in my eyes is, that there were actually THREE years of sets in one catalogue. This of course means, that despite having only a small amount of new sets per year, and only one faction per year, you probably had a wide variety of sets around.
I think it would be possible to spread the current three factions out, to give them each a couple of more specialized sets. To be fair I have no idea how to give the Pilots interesting sets that are better than the current Interstellar Spaceship, but I think the Scientists and Engineers could use some reinforcements.
