Like many games of its type, it has an addictive loop that will often have you looking at the clock one minute, then looking back to see that five hours have suddenly passed. There is a lot to this game that takes up your time, between managing your realm, dealing with your offspring, engaging in warfare, and maybe even assassinating political rivals! It's a robust, strategic experience that feels complicated at first, but ends up becoming quite intuitive once you get a feel for it. If you like history, you basically get to create your own history and influence the course of events across the Middle Ages. My one big knock against this game is that for a game called CRUSADER Kings... participating in Crusades sucks! In general, warfare with AI allies is often an exercise in frustration, so you do have to compensate for those shortcomings if you're hoping to take on a powerful enemy. Still, I've put a lot of hours into the game, and I'm sure I'll put in many more.
