I have been thinking about this for a while now. The RP potential could be excellent, with plenty of room to make things very difficult for myself and other group members.
The one technical drawback is the voice sets. When I charge an enemy and fight, etc, the NWN engine will have me making all sorts of remarks. Is there anyway to have a "blank" voice set, or one with no actual speech? Or some way to turn of the sounds not just for those I hear, but for the ones I would make?
Maybe there could be an ear for sign language?
Any thoughts would be appreciated.
