Isn't it, though? 
Every time a friend asks me to recommend a PC game, the first I recommend is Crusader Kings. The second is Europa Universalis III, but there's something about CK, especially with the dynasty dynamic, that makes you hang on every single day, week, month, and year. You want to play for just a little while longer, to see what happens. Will your eldest son inherit? Will he die prematurely? Will the death of your lord spark a civil war amongst his offspring? Will you inherit the throne of Byzantium now that the childless Comnenid emperor, into whose family your great-great-great grandfather married one of his daughters, has contracted the plague and is like to die? Will the crusading forces of Christendom manage to eject the Moors from their European foothold in Iberia? Will the last descendant of Edward the Confessor, exiled to Scotland, rampage into England from the north and reclaim the crown which William the Bastard so unjustly stole from him?
It's definitely addictive, and never, EVER boring.
By the way, there are now nearly 2,000 signed up on the CK2 page! Please join up and become a fan of this petition for CK2 on Facebook. Everything I described above could be made even better with a new game using technology and systems that Paradox did not have available when the original Crusader Kings was released six years ago.
