PS1:
Alis: Anarchist, but only by necessity; Possible Monarchist or Republican (as in establishing a Republic), open-ended.
Odin: Same. Not too much to be said of these folks.
Myau: Kitty-cat-ocrocrat. However, he establishes a closed off seemingly libertarian musk-cat society.
Noah: Absolute Anarchist; See Lutz.
Mayor/ Governor: Oligarchist--regardless of Alisa's choice (goood fanfic title,) our Mayor will be one of the few still in power most likely.
Lassic: Authoritarian Kleptocracy; Tyranny; Despotism.
PSII:
Mostly Anarchist and Libertarian. I see most content by allowin each city rule on its own rather than a Federation or Republic.
Rolf: Totalitarian Democrat/Technocrat, then Anarchist, by necessity, then Democrat (as per PSII narrative after defeating MB)
Nei: ?
Rudo: Anarchist by necessity. Feels above the law to hunt monsters and join Rolf's crew.
Hugh: Green Party.
Amy: Socialist. Its tough to meet a physician without traditional socialist views, even if they have some capitalist traits. Social Democrat, I will concede to.
Anna: Anarchist, in the way that I feel she'd best support no form of government.
Kain: Same as above, but less of the feeling. I think he would best prefer to remain Apolitical and leave it to the rest of society, if a words exists.
Shir. Kleptocracy. But really, an narchist by necessity and the disregard of laws, possible capitalist coming from wealthy family, with a liberal mindset compared to the average wealthy person.
Commander/ Governor: Technocrat, Totalitarianist, with Democratic Republican sympathies later in game.
Palm Government: Totalitarian, per the idea that they call all shots, or most, even if guided by MB. In English translation, we are led to believe they are the ones who tried Rolf & Co. via trial absentia, and decided upon the sentence.
Lutz: Absolute Anarchist. Libertarian. Seems content to prefer each city or group of people govern themselves, rather than Federation or a Republic. Such as his own colony. Rebels against any or most forms of collective governing as well an authoritarian one.
Tyler: Same as above.
Mother Brain: Programmed as Absolute Authoritaran Technocrat.
[Reveal] Spoiler:
Earth People
PS3:
Mostly Monarchists. Wont list all of course.
Ryan: Democratic Republican.
PSIV:
By and large, some form of Libertarianism where each city, town, etc governs itself. Nobody to my knowledge objects to this.
Wren: Not a Technocrat. Shuts down
[Reveal] Spoiler:
Daughter
Demi: Same pretty much.
Any other ideas? I'm sure I missed several. Or may be plain wrong.
