Just had a thought and wondered if anyone else has done it or thought it through:
For an RPG style game would it make sense to use pathfinding for the NPCs?
Think like in a town and cut scenes, as in not action. That way when you want to have them move they will move around the player and other NPCs instead of in the classic RPGs where random townspeople would run into you and walls and such.
This would mean having to give the player and all NPCs the solid behavior, correct? Will that have any unwanted affects?
