Crusader Kings II

Crusader Kings II is a dynasty simulator, where your goal is to guide

your dynasty through the middle ages. It's very large game and this

episode can only scratch the surface.

You're a ruler of some kind, like count, duchess, king or empress to

name a few. You need to manage vassals in your realm and keep your

neighbours at bay. When you're not busy with that, you can relax and go

hunting, build an observatory or join a secret society (to name just a

few).

Couple first games will be overwhelming, but it'll get easier when

you start realizing how things affect to each other and what kinds of

things you can do.
