One thing I truly fear is that Galciv II with be as politicly simplistic as Galactic Civ I.
I want to be able to see what people's political beliefs are on my planets, I want to be able to have alien subjects in my realm, with a special capacity for mischief, including the possibility of seperatists resurecting dead civilizations. I want to have political parties, with their own leaders and cabinets. I want the pie-chart polls to be slightly innacurate, so their is an element of uncertainty as to whose going to win the election if the poll is close. I want there to be the possibility of a govermental change, allowing you to step into the shoes of the newly elected leader.
And I want to have a system of planetery loyalty/disloyalty that is key to whether they rebel and split away from your civilization (expecially important for aliens under your control) and affecting planetery morale. Loyalty increases naturally to +100% when morale is high and things are good or when there is a change of government in a democracy. However a section of things can cause disloyalty
Prolonged low morale
Great difference in political beliefs or morality (which may be caused by cultural pressure)
Bieng conquered by another race (half of a planets loyalty is turned into disloyalty when a planet is conquered by another race ie +100 turns into -50)
Nasty events
Destabilisation
Is is possible for a planet to be misrable and yet have high loyalty or vice versa (if they get enough bread and circuses), but loyalty will eventually shift to reflect the planet's morale given enough time.
Rebellions
Rebellions are the culmination of a low morale and a low loyalty in a planet. Revolts turn a planet into either a member of another civilisation or part of a galactic movement (such as the fundementalists) or part of the leugue of Independant Worlds (I leugue) or will ressurect a dead civilization.
Joining another civilization
This is likely to happen only if the planet is of a civilizations ruling race. For example a rebelling Torian World will join the Torian Confederation (if it exists).
Joining a galatic movement
Sometimes randomly, galactic movement events trigger throughout the game. After the point of a movements creation rebel worlds may decide to join it. If it is the first world to defect in such a way then the galactic movement becomes a civilization. If the movement already exist as a civilization then the world will decide to join it. Galactic movement that are civilizations count all species as the ruling race and can thus culturally assimilate any world that is unhappy and disloyal civilization. However if a movement conquers a world of another civ then the disloyalty penalty still applies.
Joining the I Leugue
The I Leugue counts as a galactic movement, except that it is always active and is the ordinary fate of disloyal planets. The I leugue isn't very warlike and will never declare war on another civilization.
Ressurecting a dead civilization
A civilization that has been conquered can still be reborn. Rebellious planets from a dead civs race will reestablish their civ. If it is a major civ it regains a place in the U.P. The civ starts life with 100bc in cash per planet, and is at war with the civ that it broke away from. It takes control of any ships that were built on the planet in the past and any orbitting ships regardless of origins come under the control of the restored civ.
