Prodigal Empires is a developing science fiction background. The origins are left intentionally vague.
Essentially the Earth suffered various disasters and wars in a near future leads a large portion of the population to vacate the planet on generation ships. These colonists travelling at a slow pace across space chnage culturually and settle various worlds where humans being humans they fall out and start fighting.
A later generation of colonists with faster than light travel spread out amongst the stars meeting and fighting the already established. Eventually Earth collates into a number of great power, such as Maphilindo, the United Americas, the Christo-Communards who also join the colonising game bumping and bashing into the human colonies. They bash against the generation ship powers who have conquored territory like the Holy Stellar Empire and the Niptish Empire.
There are also aliens out there some weaker than us and oppressed, others stronger and spoken to very politely.
This background is being developed as a roleplaying background but is also used for wargaming.
A fight between two Italian descended generation ship settled space colonies was fought using Full Thrust known as Revolutionary Biscuits of Italy (because what blog is complete without an Alexi Sayle gag inspired campaign.)
