How long do people typically play for? My sessions generally last from 6-8 hours of play.
My Players can easily weddle away 3 hours "politik-ing" with one faction or another, diplomacy, bluff, sense motive and gather information checks being the bulk of the dice rolling, and we have gone entire sessions without combat due to creative talking by the group.
I generally try to plan for 3 possible combat scenarios and 2 pure interaction scenarios. However with my group you never know what will trigger them, they might talk for hours with the leader of a necromantic theatre group and part friends, and then chase down some NPC from a faction they are opposed to and beat the snot out of them.
