No story sandbox, siege battles, a lot of reading. You start as outcast with short back-story from customization of your face and stats. Improve your skills and help lords to earn renown and money.
Mostly focused on fights, fetch quests and fighting again. You need only money to fuel your army as without them you will have no possessions. Lords will not die, they will create wars and you can not defeat them entirely, thus maintaining good relations is important to some. Story is really missing part.
