In Warband, you can carve out your own kingdom and get lords to kneel to you, basically becoming their liege. One of the big issues in Mount & Blade is that while you could rebel against your liege, you couldn't get other noble houses to support you that well.
Warband should beef up the strategic aspects of the game a bit. So here comes Warband, an expansion that looks to address some of the issues. However, it did have some flaws, like lackluster graphics at times. It made for an amazing immersive experience, as well as a wholly original one.
Last year's Mount & Blade was a cool blend of action, role-playing, and adventure set in a medieval world inspired by our own.
