Vicky's quiz All First-Level Subdivisions of Africa on a Map is already challenging enough if you remove the lesser populated subdivisions! How many of the first-level subdivions of Africa with more than a million inhabitants can you name?
Good job putting all of this together. I only wish that you'd be a little more consistent with type-ins. For example, just Rabat and Tangiers are accepted, but not Fes, Casablanca or Marrakech. (And also not the standard type-in Addis Abeba).
