Roleplaying in the game makes it a lot more entertaining. Allowing the game to screw you over, instead of min-maxing and powergaming, also makes things more entertaining. A case in point: in a recent game I played (with my mod) as a West African Muslim, my ruler designed character got depressed. Okay, whatever. Then he embarrassingly lost a war against a OPM even though he had three times as many troops and better generals to boot. I decided to roleplay and make him commit suicide (for those who don't know, it is something your character can do via decision if they're depressed). He had two healthy sons, one already an adult, so I figured from his point of view it was alright. So son #1 inherits. Son #1 does pretty well. He also marries his dad's other wife, the one not his mom (Muslims have multiple wives, for those who don't know) because it's funny. However, Son #1 dies in battle a few years later, leaving his underage brother, Son #2, to inherit. Son #2 has to suffer through a crappy regency by his corrupt steward, is also the only remaining male of his family, but manages to become best friends with a girl in his court that he later marries and becomes lovers with (aw).
I dunno. The game is better when you don't play it as a game.
