In every RPG game there's the Overworld map, the actual map and the mini-map. With RPG Action, making maps will be easy. Just layout the actual map, and the programme will generate the mini-map (including fog-of-war if you wish) and overworld map. It will even automatically stitch together the overworld map based on how you lay out the entrance and exits.
See example of auto-stitching. You can of course make adjustments.
