In P&P every combattant is considered flat-footed until he gets his (first) action (not sure if thats the same for nwn, although I spend endless hours playing it *blush*). Therefore the initial situation for both duelists is the same, creating a "high noon" situation. The duelist with the highest Iaijutsu skill roll gets the first attack then. So its not dishonourable because both are in exact the same situation

. As I said, that skill is indeed absolutely useless for normal fighting in both P&P and NWN and requires special scripted events in custom modules I would think. Not 100% sure, but I think in P&P that skill is indeed only usable for those duels. Personally, as an P&P DM, I would say that that PC and skill is indeed quite specific and useless in nearly every campaign

. That goes, however, for the whole rulebook it is taken from, "Oriental Adventures", I would say. As the name says, the rules presented there are made for a specific oriental setting, and in a straight samurai campaign that skill and class may make sense. The material that COULD be used in conjunction with all that other D&D stuff is taken and reworked in the Complete Series I think.
That said, I can of course absolutely see your point and would indeed not buy that specific rulebook for D&D 'cause I have no love for far eastern settings out of the occasional anime series

. The only point I was trying to make is that there are indeed some PCs, that are quite useless for around 95% of the gamers but do somewhat add to the settings or are just for the fun of it. The best example I was confronted with as a DM is the PC "Evereskan Tomb Guardian" from the Faerûn Rulebook "Player's Guide to Faerûn". That PC does practicly nothing outside, well, Everaskan Tombs

. That makes it unbelievable useless for every campaign outside of that particular elven city, and even for a campaign with that setting its probably only useful for npc's or just as a background for the pc's :|. But there are still other usable PC's in that sourcebook, and if not, than no one forces one to buy / use it
