But then... they... die??
this is probably why you cannot build more.
Pretty epic what you did there :D
However, how would you want a story full of humans if... there's no humans in the game? Like, at all?
in a galaxy where the last organics are the chickens, who are fighting s desperate battle for survival against the robot swarms a rather improbable event happens, a race of space-faring warriors composed entirely of hermaphroditic (but female looking) lesbian space pirates arrives, with no leader, no means to go back, and no desire to be good… they immediately turn on each other and in the fighting the ships that brought them there are destroyed so they have no choice but to take control of the “local” forces and so…10.000 years later only 2 factions remain, the swarms of The One who believe the best… leadership… is an iron fist who holds the whip of command and the fractious but ever multiplying Meck Conglomerates who battle for the belief that all things are better done as a in as big a group as possible, leadership included.
Now zero-k still has a post-apocalyptic world with no humanity, but it has (pirate) space-lesbians that people can relate to, allow for most forms of fanfiction, and a line of Japanese erotic visual novels.
is it better now?
