Choose a color and draw your borders on the map, preferably colors matching your flag so it doesn't get too confusing. Go ahead and use a zoomed in picture too, because once we all start posting on the CS tab, roleplayerguild might shit itself while trying to load a bunch of bigass high res maps. This section should include geography, weather, flora and fauna of your nation, as well as include the capital. Your geography should match your location on the map in relation to the equator and your distance from the sea. It bears mentioning that unnatural creatures like dire beasts and the like are allowed, though I will be picky about what can be tamed.

This should be more generally informative of the country's past and how it has affected their culture than a list of dead kings and globally inconsequential events. I encourage players to collaborate and create shared history.

Hoo boy. This section should be the largest, and cover as many facets of their culture you can think of. I don't just wanna know their clothes and religion, I want to know what their food is like, how other countries view them, what their view of death is, and so on. Do they use beds or rollout futons to conserve space? Do they bathe normally, or is regularly being submerged in water considered unhealthy? Are there foods associated with a holiday? Do they duel over honor or legal matters? You get the picture.

Aside from the general "They have a lot of foot soldiers, a few mounted soldiers, and some archers" tell me how their military is different than any other military, and do it without listing any numbers. Do they ride something besides horses or sail something besides galleys? Do they make use of psychological, biological, or economic warfare? Do they take prisoners? Things like that. If this section includes some bullshit special group of a hundred that uses two swords because they went to sword college or something like that, see yourself to the door.

In the simplest terms, what do you import and export? Do you make a lot of things, or just one thing? Is your country in debt to another? Geography and culture will play a role here. Also, no country is self sufficient.

Don't just give me your trade relations you god damn minmaxer. Tell me what your peoples get called by racists, what your country's relation to the rest of the world is, what the popular image of your country is as a whole, etc.
That, and y'know, those trade relations.
