Automating the map creation process
There are several tools available that allow you to quicken up the map creation process.
Vision creation
You could just start with a map in SVG format. These can be most easily found on Wikimedia Commons or a Wikipedia in your language.
Various raster (ie., not SVG) maps are viable for conversion to SVG format - two most used tools for this are potrace (bundled with Inkscape, available as Path -> Trace Bitmap.. command) and AutoTrace (available for online use here). The clearer the map, the better results you can get - single-color borders on single-color background, or differently colored territories, work best.
IDs
Inkcape extension plugin for automatically assigning selected Paths ID is available here: https://dl.dropbox.com/u/89026778/WLExtension.zip
Other tool that makes every path have a territory ID automatically can be found here: https://www.dropbox.com/s/0agz210n839tvdq/warlight_territories.exe?dl=1. It only works on Inkscape-made maps.
Centerpoints
A tool that can create centerpoints is available on forums: http://warlight.net/Forum/Thread.aspx?ThreadID=2452. It calculates the centroid of every territory-polygon and places the centerpoints. It does not work correctly on multipart territories.

Connections
A tool that can create connections is available on forums: http://warlight.net/Forum/Thread.aspx?ThreadID=2668. It checks every pair of territories and every pair of their points - and considers them neighbors if the distance between any pair of points is less than 5 pixels. It does not work correctly on multipart territories, can take a long time to finish (up to a few hours on large maps), and may be overzealous, connecting territories that don't actually touch (but are pretty close).
