This expansion continues to take CKII down the path of Role Playing Lite by giving more power to vassals and allowing you to influence your Kingdom's direction even if you aren't in charge. It improves the interest level in the game during those long periods while waiting for something to happen. It forces you to think before ticking off your vassals. It also makes playing as a Duke in a large kingdom or empire more interesting as you aren't left with just revolting against your liege as your only option.
