Its not a liberal bias so much as a whig one, things that lead towards the present are rewarded. And modern false concepts about history, the denial of historic rights and liberties and in order that people to-day can think that our society is better than all those that came before it. pretending that people in the past had not rights so we dont have to admit they had more rights than us. But thats not the games fault and because the whole world for the last six hundred years has thought like that it cant go against it.
ON TOPIC however, the new POP allows for an end for this.
Its give the possibility that should conservative, reactionary and fascists hold the Great Powers and influence on the world for the bulk of the game itd be nice for the possibility of them winning in the end, the capitalists shut down, corporations and fianance broken and replaced with the resurrection of the independant shopkeeper and craftsman, the enclosers abolished and common land returned and all that deep and merry english ideological utopia dreams made flesh.
Capitalists, Craftsman and Clerks slowly changing to artisans maybe bureaucrats or soldiers and officers or into the clergy too depending on what direction the world and that particular country is going rather than the global trend towards the liberal and mass industrial occupations, mostly to artisans though as they make it work. Inventions only for the alt-lines that give technological advances that benefit the local and independent workforce, guild economics and politics, militarist societies or the new feudalisms. Progress, but not towards today, to other places, depending on the situation.
If Conservatives and especialy Reactionaries should hold influence over the world then rather the late game be the growth of the monopolies and the centre parties on both the right and the left adopting liberal positions if there could be some global value or modifier that decieds which ending the story will have, which road the world should follow, which ideology should become dominant and shape the policies of all those around it in the late years of the game before the break-out of the utopian ideologies after the war, or even including those where all the world heads to radicalism. Different Paths of History so that each game might not end up Liberal.
So That the Player can shape the course History, not just that of the nation he guides. Isnt that the point of the game after all.
