The user-created catalog will even be populated with plenty of content right at launch, because Shafer tells Bitmob that "you can import Civ 4 maps into the world builder and convert them into Civ 5 maps, including all the units and cities and stuff on it -- the conversion process will just do that for you automatically." Presumably, the process will also translate the maps from squares to hexes, which means Shafer and everyone else's maps from the last Civ are just a conversion away from being playable in the new game. Which is good -- some Civ fans would have a tough time without their Middle Earth maps.
