They took a conscious decision to emphasize the mundane parts of life, turning CK from a GSG about managing a dynasty into "medieval sims+". How many times can the same event aka "activity" transpire before it stops being interesting? I don't deny they look fun, and probably are fun the first time, when a new player is actually attached to his toons.
People keep fond memories and take ownership of stories that resulted from emergent gameplay. The aristocratic fun in CKII lies in being a careful rules lawyer who is ready to improvise on a theme, when the conditions arise from the environment of AI-controlled characters.
Like "that one time" when you were at war with the HRE and just then the king of Danemark offered you a marriage between his son and your third daughter which you previously, luckily, denied to someone else, and this came just in time for you to call Danemark into the war and with their 5000 troops plus some additional mercs you hired, you managed to win. How does something like this compare to "I got measles when I travelled to my uncle's county, lol".
I guess they are going for emergent gameplay that creates such stories to be remembered, but who is the target audience here really? Also, if you try to generate "emergent gameplay stories" every odd hour, they stop being memorable or remarkable.
