One thing GURPS Dungeon Fantasy specifies is that a character needs to be mapping if the players want to make a map.
"For the players to be allowed to make a map in the real world, a party member must serve as “mapper” in the game world. He requires ink, paper, and two free hands. He can't carry a ready torch, shield, weapon, etc."
- GURPS Dungeon Fantasy 2: Dungeons, p. 6
In my current game, Nakar does most of the mapping. He has a (pretty silly) item that lets him draw a map on paper held on the inside of his shield - basically a shield-mount clipboard. I don't actually care which player does the mapping, as long as one character is set up to do so.
In fact Nakar's player maps sometimes, and another player maps another time. But if Nakar doesn't show, and no one has ink, paper, and the inclination to map instead of staying armed, no mapping can be done.
Does anyone else play this way? Is this very unusual?
I know for us, this makes it seem more real. My players have even bought into it so far as to pay to make a copy of the map and leave it in town, in case the map gets lost and they need to replace it (or need to buy it for their new PCs, in case of a TPK). But I can see some people disliking this.
If you allow mapping for the PCs without a mapping character (IOW, no one has to have ink, free hands, etc.), does this every affect the verisimilitude of the game?
