The Empires No One Suspected-Make a map showing a large empire that no one would have though could happen before it did. For example the Mongol Empire, the early Caliphate, etc.
More Than Words-Create a map that stands on its own. Other than labels on the map itself, the map shall have no accompanying explanations, either on the map or in the forum.
No, WE'RE The Real Government-Make a map showing a country during a civil war that's gone on long enough that most people outside the country just think of it as having split into multiple countries. Examples from OTL would be Korea with the ROK vs. the DPRK, or China with the PRC vs. the ROC.
The Ocean is Full of Terrors-Make a map showing a state founded by a seaborne conquest or migration.
The Return of the King-Make a map showing a country where the ruling dynasty was removed from power, but later returned to power. “Dynasties” in countries with non-hereditary forms of government (like the Kennedys or Roosevelts) are permitted.
Special Treatment-Make a map showing a Hong Kong-style Special Administrative Region where a small enclave of a country is, for almost all intents and purposes, separate.
This Too Shall Pass-Make a map showing the same region in two different time periods - one during a golden age of prosperity and power, the other during a dark age of regression and chaos. Which period comes first is up to you.
To New Lands!-Make a map showing an alternate Migration period. Ethnic groups in odd places is encouraged. Map can be set any time after the Migration period. [that, right there, is my god-damned map-fetish]
I'd also like to propose another one-Hunny, I'm Home!-Make a map depicting a Nomadic-based State. For example, the Huns or the Mongol Empire
