Spieldesign - Neo-Feudal system

Feudal hierarchy

Emperor

Controls multiple star systems.

To proclaim yourself an Emperor, you have to be the sovereign (King) of at least two star systems. There is a social pressure to do so, in fact. You don't automatically lose your Emperor title when you're down to just one star system, but those who conquer the last one from you can strip you off it by force.

King

Controls a star system.

To proclaim yourself a King, you have to be the sovereign (Duke) of at least half of the habitable planets of the star system if there is no other King of that system, else at least two-thirds of the star system if there is one, to wrestle control from him.

Duke

Controls a habitable planet (+ territories subordinate to that)

Baron

Controls a planetoid of major asteroid, or a habitable planet's state

Religion

(TBD)

Solar systems

Solar systems - as well as everything on that scale in the game - are positioned to a precision of 0.001 ly (63.240 AU) and treated as stationary for the course of the game. A jump into the system happens inside this precision's limits. Major planets are assumed to be all inside these limits (and thus the max distance from the baricentre should not exceed 63.240 AU, but there's no check to prevent that).

Comparison of the solar system:

• Outermost planet (Neptune): 30.332-29.810 AU
• Outermost planetoid (Sedna): 937-76 AU (0.015-0.001 ly)
• inner doughnut-shaped (Hills) Oort cloud 2k-20k AU (0.032-0.316 ly), outer (spherical) Oort cloud 20k-50k AU (0.316-0.791 ly).
