Question like the topic suggested, how do I write a Nation? Like I understood that we roleplay the nation's citizen, but how about policy? I have no education in policy making, fiscal budget,... And while I had been spending a lot of time in reading wikipedia pages about the nation's policy/ agenda, how do I make the policies and the subsequent situation to not be an outright nationalist's wetdream? 

Any suggestions on policy making, writing, and the whatever that related to nrp are much appreciated.

The most basic principle of writing political stuff is to approach it like this: all parties are the unions of individuals over a unified purpose or interest. Or to take it further a broad class interest. The way a state functions depends on who runs it, and the politics of that state is how that class works. A lot of it takes some creativity or even fore-knowledge on a subject, or even just keeping up with the news if you're doing things in a more contemporary setting. And don't worry about fiscal budgeting: that shit's so boring that no one really focuses on it, and it might only exist to fill out the setting but doesn't dictate much because most of NRP is to my knowledge not full of accountants. You can get away with a generalized understanding of a budget: there's only so many resources available to a given organization or state-body, and those have to be allocated; the best running functions of a thing are the most well funded or the most corrupt.

But as the more interesting stuff: again it depends on era. The easiest thing to write about might be feudal or prior societies where the functions of a nation state are poorly developed or not even developed at all in the least (national identity and the existence of the nation-state is after all a very new thing in human history, and there are parts of the world where it's still not yet fully matured). In the case of the feudal society, you have a government run primarily by the aristocracy. The interests of the aristocracy can be best described as personal networking and feuding. The aristocrats are building alliances between families and within families to compete with their rivals from within and without and to acquire the most basic of resources: land and man power. Advanced finance doesn't really exist, because the intrigues and the conflicts among the aristocracy most often lead to open war and the ability for a given noble to raise and assemble the most fighting men is crucial to exercise power against someone else because it's often just a matter of removing one rival's people from a location and replacing them with your own. Feudal social arrangements often feature the most naked and basic hierarchies: peasants are tied to the land and may never leave it, because they are directly or indirectly owned by a noble that owns the land they are allowed to live on for a rent or because they have some sort of fealty to that lord. That lord in turns owes fealty upwards to someone else; though they may not be always loyal to their capo. And so on up the chain of command to the king. The lowest does not exert any influence on the king, and the king's power just often becomes more a vibe the further down it goes (historically for example: the King of France has had practically no power for as long as the title of "French King" has existed).
