Hexographer Pro Version
The pro version of this easy to use Hexographer world/kingdom map-making program. The pro version allows you to customize icons, add notes to the map, expand an existing map with new rows or columns of hexes, among other bonus features. It is widely recognized as the easiest to use map-making program that allows you to make maps in the classic 0e and 1e fantasy styles.
Note: This doesn't come with a code to the new Hexographer 2 (aka Worldographer) currently in beta. For that, see our Hexographer/Hexographer 2 product which has a license to both.
