EotBeholder on Deviantart nails decades of derivative genre fiction and gameplay with "the only fantasy world map you'll ever need."
Wow, almost four years later and this thing just exploded. … To anyone asking for permission to use this for their own campaigns… I mean it hardly qualifies as "original", so as long as you're comfortable stealing from someone who steals from the people who only steal from the best, knock yourselves out :)
If I could make some additions (which I suppose I could, but, nah) I'd call out the Boring/Doomed Pastoral Village somewhere in the Tiny Bickering Fiefdoms or the Land of Poncy Knights, and also add a Giant Wall to Keep the Monsters Out. Giant walls are so hot right now.
I love the comments and tweets from fans of specific franchises (such as Forgotten Realms or Riftwar) who think it is specifically a parody of their favorite fantasy world. See TVTropes' entry for the fantasy world map and, specifically, the left-justified fantasy maps.
The map of Allansia from the Fighting Fantasy gamebook series is a nice professionally-drawn example.
