I thought the 'rival adventuring party' thing in the Kickstarter was promising (one reason why I backed to that level). I hope they are implemented as more than just a random encounter; if they are given some build-up in terms of hearing about their exploits from townsfolk, encountering a destroyed caravan or group of monster corpses they've left behind, or them racing you to a plot goal, then that gives a good impression that your party is not the only competent force in the world. Yes you are lucky and have abilities way beyond the normal inhabitants of the world, but you are competing against rival adventurers of similar power then there is more sense of earning your rewards, vs being pre-destined to achieve them. Throne of Bhaal did this fairly well with the rival Bhaalspawn I thought.
