Also, remember that in RP, your character would not have a little dot on his map saying where he is at the moment ...
So you\'d have to look at your map of the caves, wandering around a bit, and trying to remember where you are in relation to the entrance, even though you have a map. You\'d look at the map for landmarks and try to find those, just like a map in the real world. You could count left and right passageways on the map, so you could get where you want to go in the world, but if you took a wrong turn it could really screw you up.
Pretty much a map that was just a single image, without player location, but including various landmarks like \"weapon shop\" and \"three waterfalls\" would be the best for RP. Utility-wise, it might not be the best, but the player should experience some of the difficulties that their character would trying to use a map.
It would be nice to be able to add text notes to a map when it\'s open and have them stay as data in the map item. People could make maps with cartography and then add special notes that other cartographers might not. Then again, this isn\'t simple and it\'s not neccessary. They did it for Thief 2: Metal Age and it rocked.
EDIT:
Also, all NPCs could have the same speech set for a given area, say a town, that if you asked for directions they would tell you the major things in town. If you asked about those things they would tell you how to get to them from a central starting point in the town. So it would be a paste job for all the npcs, written once per civilized area.
Of course it would be better if the directions were all slightly different, since you wouldn\'t want everyone to speak the same way ...
