More than just a civilization simulator, CKII places.

I suggest you watch a few videos, then start up a game on your own and experiment. Crusader Kings II, a grand strategy game developed by Paradox Development Studios, is a dynastic medieval simulation game: starting as early as 769 AD and ending no later than 1453 AD, you play as a landed noble struggling to keep your dynasty alive and in power. The tutorial was published in August 2014, and while not 100% up-to-date (several patches and expansions have been released in the meantime, resulting in some changes to the interface and game functionality), it still provides a superior introduction to the user interface and the concepts of 'feudalism' that permeate the game than the in-game tutorial. YouTube "Let's Play" Gamer 'Arumba' created a Tutorial Series of videos to help new players learn the basics of the game. This might sound boring, but I've found it a sound strategy to learn this game CKII has an incredibly steep learning curve (I've played over 750 hours and don't consider myself an expert yet).

I've found the best place to start is to watch games recorded by more experienced players. While it does an ok job of introducing you to the user interface and some very basic game principles, it doesn't go far enough in explaining the way the in-game world works. Unfortunately, the in-game tutorial is somewhat.
