Indicators on it would show the level of resources (gold, timber, horses,
population) for each region. The map would be generated centred on the
character requesting the map and showing a variable distance in all
directions, up to a maximum of 2 months travel, but specifiable by the
player. In the case of multiple characters in a faction requesting maps, if
they are within the 2 month-travelling maximum distance, then a combined
map is produced showing the entire region which covers them all.
A handy addition would also be for a flashing "*" to appear on the map to
indicate the presence of anyone you have declared as hostile.
Of course, this might all be pushing the code a bit far and may tend to
produce rather large mail files.
