Well you pretty much covered Europe, Asia (with the upcoming supplement,) North America (minus Central America,) and Africa.
That "only" leaves South America, Arctic/Antarctic, Australia, Oceania, Mars (Barsoom,) Venus, the moon, and the other 5 (or 6 by Victorian Lights) planets to cover.
Yes, nothing left there to see.
Gracias,

EDIT: Oh, and the center of the hollow earth...
