This is by far the best mapping program I have ever used. It combines the ability to craft the appearance you want with the functionality needed for game play. The list of features is very long indeed but the highlight of this program is actually the developer. He both welcomes and listens to feedback from users in order to improve on an already impressive map creation tool. It is very easy to layout the landscape of the land using default or custom icons. With links you can open a city map just by clicking on the town icon or or navigate down stairwells in a dungeon, each level opening in either the same window or new windows as you click links. With automatic maze/dungeon generators you can quickly add to your world, when players do the unexpected. I really can not say enough, just that I hope you will give this amazing program a try.
