I, for one, loved the little, seemingly off-hand bits found in the Tarsus module. The planetary comm system and the voting system to be specific.
Tarsus has a personal sat-comm system of sorts but, thanks to hardware limitations, it only works between certain longitudes. Great Ghu, that just screams for use in an adventure!
Voting is even better. Everyone who was on world at a certain date centuries in the past was given the vote. Heirs recieved the vote when they original holder died and multiple heirs recieved fractional votes... Ooooh, just think of the shenanigans you can have with that bit!
Then there is the distinction possibility of a previously unsuspected Sword World refugee group coming into a whole batch of new votes! First, the planetary court ruled that free trader crews present on-world during that distant vote award day should be given votes too and now the surprising discover of a TL0 group of forest dwelling 'wildmen'; descended from Sword World refugees who arrived centuries ago, should have the vote too!
The mind boggles...
Sincerely,
Bill
