One of the more recent features available from Wikia is Maps.
- "Wikia Maps allows users to create interactive maps for real world places, images, or fictional worlds. Map pins can be added, edited and customized by the community to create a rich mapping experience. These maps can also be embedded in articles or external websites."
I think Maps would be a good feature to enable on the wiki. I'm sure users will find great use for maps of North Korea and Venezuela with important features and locations pinned.
